Most of our customers use financing rather than capital outlays to grow their manufacturing business, and they have a number of smart reasons for doing so:

1. CHEAPER THAN CONTRACTING YOUR ASSEMBLY OUT

Companies can spend $10k and more a month contracting out their manufacturing, but you can typically bring an SMT assembly line in-house for a third of that when you lease or finance your line, and many companies already have a person on payroll who can operate the equipment.

2. EASIER TO GET THE GO-AHEAD

Financing typically requires fewer internal approvals than a capital purchase, making it the faster and easier route to an assembly line install or upgrade.

3. INCREASE YOUR PRODUCTION CAPABILITY SOONER THAN LATER

Rather than waiting until the money is there for a major capital outlay, with financing you can start the ball rolling on ordering, receiving, and installing your new equipment right away, allowing your company to benefit from increased capacity and capability much sooner than you might have otherwise.

4. GET BETTER EQUIPMENT

Financing gives you more purchasing power than a cash purchase. This means you can focus more on your goals than your budget.

5. ROLL IN INSTALLATION AND TRAINING

With a cash purchase comes the temptation to reduce costs, sometimes causing essential aspects like installation and training to be cut, but installation and training can have a big impact on how quickly your new equipment or production line gets up and running. Financing allows you to roll this cost into your payments.

6. PRESERVE YOUR WORKING CAPITAL

Making a large cash investment in your production line leaves you with less ability to put that money to other strategic uses, such as growing sales and increasing inventory.

7. IMPROVE CASH FLOW AND EXPENSE PLANNING

With financing, your new equipment becomes a regular monthly expense item in the budget.

8. OBSOLESCENCE PROTECTION

At the end of your lease term, equipment can be purchased at fair market value, upgraded, or swapped.

Introduction

• The industrial ovens used to reflow solder on a printed circuit board are intricate tools. Using a combination of radiated heat and heat convection, the solder reflow oven delivers a carefully regulated flow of consistent heat to the PCB. This process completes the assembly of the board by melting the solder to form good solid solder joints between the components and the board.

Failures and Maintenance

• When the red light is on, the buzzer long beeping non-stoppably
  Cause: Control buzzer time relay does not work; control thermocouple opens circuit; control section of the main circuit SSR is damaged.
  Solution: Check the control buzzer time relay; check the control thermocouple; check the control section of the main circuit SSR.
  2. The system automatically enters the cooling state
  Cause: PCB dropped or jammed; transport inlet and outlet electric eye damaged.
  Solution: Take out the dropped board; replace the electric eye.
  3. The start-up process heating area temperature does not rise to the set temperature
  Reason: Damaged heater; Heating point pair faulty; Solid state relay output disconnection; Exhaust too large or unbalanced left and right exhaust; Damaged photoelectric isolation device on the control board.
  Solution: replace the heater; check or replace the electric thermocouple; replace the solid-state relay; adjust the exhaust valve air plate; replace the opto-isolator.
• Emergency switch pressed, the system is in the waiting state
  Cause: Emergency switch is pressed; line is damaged.
  Solution: Reset the emergency switch and press the start button; repair the circuit.
• Inaccurate counting
  Cause: The sensing distance of the counting sensor is changed; the counting sensor is damaged.
  Solution: Adjust the sensing distance of the counting sensor; replace the counting sensor.
  

Cautions

• Reflow oven must completely reach the set temperature (green light on) before starting to solder.
• In the reflow soldering process, observe the temperature change in each temperature zone often, the change range is 1 ℃ (according to the reflow oven).
• When abnormalities occur in smt reflow production, stop it immediately.
• The size of the substrate should not be larger than the width of the conveyor belt, otherwise cardboard accidents are likely to occur.
• Before reflow soldering, based on documents or component packaging instructions, the components can not withstand the normal welding temperature must be taken protective measures (shielding) or not be processed by reflow soldering, instead by post-welding with manual welding, or welding robot.
• In the reflow soldering process, prevent vibration of the conveyor belt, otherwise it will cause displacement of components and disturbance of the solder joint.
• Regularly measure the amount of air exhausted at the reflow oven vent, the amount of air exhausted directly affects the soldering temperature.

Cut and Clinch Footprints

The cut and clinch cuts the component leads after they are inserted

through the PC board and then clinches them against the underside

of the PC board, securing the component in place.

At present, the automation level of the overall industry processing technology is average, mainly because the special equipment is relatively mature. First of all, small and medium-sized enterprises (small batches of products, many types, too large size range, etc.) have a low level of automation, mainly focusing on special process equipment + retractable board + labor. The medium and large enterprises (large batches, relatively uniform types and specifications) have a higher level of automation, mainly focusing on special process equipment + retractable boards + industrial robots, with manual assistance (inspection, maintenance).

On the whole, the demand for automation transformation of small and medium-sized enterprises is still relatively weak, while medium and large enterprises are on the contrary. Whether it is a newly planned workshop or an upgrade of an old production line, they are actively planning the participation of robots (industrial + AGV), aiming at PCB upstream. Raw materials need to build smarter warehousing; for the PCB factory, a more complete automatic warehousing system is needed, and it is best to integrate ERP, MES, etc.

Although the reality varies widely, automation and intelligence are still the general direction of development. As the basis for the development of the electronics industry, the scale and market of PCB materials and PCB boards will continue to grow with the development of 5G, smart cars, etc. Therefore, the requirements for product quality and process accuracy are higher, and automation and intelligent production scheduling will continue to grow. Demand will continue to rise.

Secondly, there are various types of products in the PCB industry, and the raw materials of the board are large and heavy. The effective transportation and management of semi-finished products or finished products during processing can improve production efficiency, so the level of automation should also be improved.

Whether it is from the perspective of product iteration or technological innovation, the automation transformation of the PCB industry is inevitable, and the efficiency and precision of industrial robots make it an important step in the transformation and upgrading of the industry.

Because PCBs (printed circuit boards) are so versatile, even small changes in consumer trends and emerging technologies can have an impact on the PCB market, including how it is used and manufactured.

Although there may be more time, the following four major technology trends are expected to maintain the leadership of the PCB market for a long time and lead the entire PCB industry in different directions.

1- High Density Interconnection and Miniaturization

When computers were first invented, some people probably spent their entire lives getting work done on computers that took up entire walls. And today, even calculator watches have orders of magnitude more computing power than those behemoths, let alone smartphones.

The entire manufacturing industry is currently in the sight of a whirlwind of innovation, much of which is in the service of miniaturization. Our computers are getting smaller and everything else is getting smaller.

Across the consumer base, there seems to be a gradual shift towards smaller electronics. Miniaturization means we can build smaller, more efficient homes and control them. And cheaper, more efficient cars and more.

Since PCBs are vital basic components in electronic products, PCBs must also relentlessly pursue miniaturization.

Especially in the PCB market, this means using high-density interconnect technology. Further improvements in HDI technology will further reduce the size of PCBs and touch more and more industries and commodities in the process.

2- Advanced Materials and Green Manufacturing

Nowadays, the PCB industry is being affected by some very real impacts such as climate and social pressure. The PCB manufacturing process needs to keep up with the trend of the times and evolve towards sustainable development.

In fact, PCB manufacturers have always been a hot topic when it comes to the crossroads of development and environmental protection. The introduction of lead-free solder, for example, required more energy-intensive manufacturing processes. Since then, the industry has been forced to find a new balance.

In other respects, PCB has been leading the way. Polychlorinated biphenyls have traditionally been made using fiberglass as a substrate, which is considered by most to be a relatively environmentally friendly material. Further advancements could see fiberglass replaced by materials better suited for high data transfer rates, such as resin-coated copper and liquid crystal polymers.

As manufacturing efforts of all types continue to adjust their footprints to a changing planet, the link between societal needs and the convenience of production and business will become a new norm.

3- Wearables and Pervasive Computing

We’ve briefly covered the fundamentals of PCB technologies and how they enable greater complexity on thinner boards. Now we put this concept into practice. PCBs are decreasing in thickness and increasing in functionality every year, and now we have a lot of practical applications for small circuit boards.

Consumer electronics as a whole has been a significant driver of PCB manufacturing and usage over the past few decades. Now that wearables have entered this space and are starting to become a reliable consumer product type, related PCBs will follow.

Like smartphones, wearable tech requires printed circuit boards, but they go a step further. They place an emphasis on design efficiency far beyond what past technologies have been able to achieve.

4- Health Medical Technology and Public Oversight

The introduction of modern digital technologies into medicine has been one of the greatest developments in recent human history. Technology now means we can store patient records securely in the cloud and manage them through apps and smartphones.

However, the rapid development of medical technology has also affected PCBs and vice versa in some very interesting ways. The onboard camera is a new development, and it is even possible to fasten an ultra-high fidelity camera to the PCB itself. The medical implications are huge: When a camera needs to be inserted into the body, swallowed by the body, or otherwise introduced into the body, the smaller the better. Some onboard cameras are now small enough to be swallowed.

As for public surveillance, onboard cameras and smaller PCBs can also assist. For example, dash cams and vest cameras have shown useful roles in mitigating offenses, and a number of consumer technologies have emerged to meet this need. Many popular mobile accessory companies are exploring ways to offer drivers increasingly smaller, less obtrusive in-dash cameras that include and include connected hubs to interact with your phone while you’re driving.

New consumer technologies, advances in medicine, breakthroughs in manufacturing, and strong contemporary trends are fascinating. Incredibly, the PCB has the opportunity to be at the heart of it all.

That means entering the field is an exciting time.

In the future, what other technologies will bring new development to the PCB market? Let’s keep looking for answers.

Keyword guide: circuit board cleaning, circuit board cleaning, PCBA circuit board cleaning, PCBA circuit board cleaning, solvent cleaning agent, water-based cleaning agent, water-based cleaning technology

Before discussing the question of “why use water-based cleaners for PCBA circuit board cleaning”, let’s take a look at the advantages and disadvantages of solvent-based cleaners.

Organic solvent cleaning agents can be divided into flammable cleaning agents and non-flammable cleaning agents according to their safety performance. The former are mainly organic hydrocarbons, alcohols and esters, and the latter are mainly chlorinated hydrocarbons and fluorinated hydrocarbons. Its process characteristics are introduced as follows:

1. H FC / H C FC: the main component is chlorofluorocarbons containing hydrogen, the advantages are good volatility, fast drying speed after PCBA cleaning, the disadvantages are relatively high price, weak cleaning ability, not environmentally friendly, and will produce atmospheric ozone layer. Destructive effect, future use will be limited.
2. Chlorinated hydrocarbons: The main representative substances are dichloromethane, trichloroethane, etc., which have strong ability to clean grease pollutants, are non-flammable and explosive, and are safe to use. The disadvantages are high toxicity, poor compatibility with plastics and rubber, easy corrosion of circuit boards, and poor stability of such substances.
3. Hydrocarbons: mainly hydrocarbons, such as gasoline, kerosene, etc. Hydrocarbons have strong cleaning ability to grease pollutants. Due to low surface tension, they have a good cleaning effect on PCBA cracks, do not corrode metals, have low toxicity and are easy to use. The main disadvantage is that due to flammable and explosive, there are potential safety hazards, strict precautions must be taken.
4. Alcohols: such as methanol, ethanol and isopropanol, alcohols have strong dissolving ability to polar pollutants, good cleaning effect on rosin, but difficult to clean grease pollutants; not easy to corrode metals and plastics, etc., and dry quickly. The disadvantage is that it is volatile, easy to burn, and has potential safety hazards in use.

If we take advantage of the advantages and disadvantages of organic solvent cleaning and avoid the disadvantages, wouldn’t it be perfect? Is it feasible? The answer is yes! Water-based cleaners were born around solving this problem.

Water-based cleaning technology is made of water as the cleaning medium, and various additives such as surfactants, solvents, defoaming agents, and corrosion inhibitors are added, and various pollutants are removed through various mechanisms such as dissolution, adsorption, and infiltration.

The main features of the water cleaning process are non-flammable and explosive, non-toxic and environmentally friendly, safe in operation, strong in cleaning ability, low in loss during cleaning, and low in cost. Because of the large degree of freedom of active ingredients, the formula can be formulated according to the special requirements of PCBA, which solves many problems. The problems that cannot be solved by organic solvent cleaning agents have a wide cleaning range and strong applicability. The flexible components of water-based cleaning agents can greatly meet the needs of customers, especially when ultrasonic cleaning and spray cleaning are used, they are more advantageous than organic solvents. .

Of course, water-based cleaning agents also have shortcomings, such as high requirements for cleaning equipment, and the need to treat invalid cleaning agents, that is, waste water.

Combining the characteristics of solvent-based cleaning agents and water-based cleaning agents, it is not difficult to find that with the strengthening of safety and environmental protection awareness and the increase of special cleaning needs for PCBA, water-based cleaning agents stand out because of their flexible formulas and components, representing the future of PCBA cleaning. Technology development direction.
