PCB surface mount ODM and OEM factories are almost everywhere in the electronics manufacturing industry. It is no exaggeration to say that as long as there is an industrial park, there is a PCB surface mount factory, which is bigger or smaller, because it is in electronics. Manufacturing, the result of a highly developed electronics industry.


What I want to say is that even in the PCB surface mount factory, the type of processing is different, the difference is also very big; just like the clothing store, each store has its own target customers; but the companies that need processing, there may be I can't understand it, I think that as long as it is a processing factory, I can make my own order.

I have been deeply experienced in the processing industry for so long; most of the processing plants are customer-provided parts factories to provide processing, PCB surface mount processing, post-weld processing, these keywords, rarely write small The words of the public, such as BGA ball, so write, some people will understand, you can only plant the ball, do not process. If this is the case, there is no customer to find the door. Therefore, for the processing plant, it is necessary to run more and find more. According to the quantity of its own products and the stage of R&D and production, find a more suitable PCB surface mount processing factory.


PCB surface mount processing plants on the market are roughly divided into the following


One is a custom-made processing plant that is professional and produced only for an industry or a product.

For example: only mobile phone or tablet, only car electronics, only FPC flexible board, only LED lights or LED display. All of their machines, auxiliary equipment, talent packages, and testing tools are all matched by such products. Although it is only a product, it is also called processing. If your product is not the one they produce, I suggest that you can look at other homes.


The other is the large-scale processing plant, which is a relatively large type, with many production lines and high production capacity. Specifically, there are two types, one is high-end precision quality type, and the other is low-end cheap type; these two production methods can be understood literally; if your product is simple and large, find low At the end, the price is naturally cheap. On the contrary, your board has a high price, the board is complex, and the precision is high. You have to find it and find the precision quality.


In addition, this type of processing factory is specially designed for small batches, PCB prototype boards, boards, and components. It is a professional lean processing factory. Although the production scale is not large, it is still very similar to traditional processing plants. Great difference.

First, the staff is very complete, similar to the general-scale processing plant; but the staffing configuration is a bit special: there is an order organizer, different from the traditional order taker, the BOM received, generally have to be sorted; PCB file, own It can be processed into a coordinate file for placement and programming, similar to the role of an engineering assistant.

Warehouse tube, patch components, plug-in components, package, value, must be very familiar, not just just order, not only incoming materials, but also the purchase of circuit boards, the purchase of components services; engineering staff, operators; more important There are hand-applied technicians, BGA chips, small components as small as 0201, all of which can be hand-picked. We have a mature and effective hand-paste method; after welding the kanban maintenance personnel, all components that can see the foot are required to be dismantled. , can be welded, can be repaired.


These are the traditional ways

Very different

Second, the selection of mounting accessories, the selection of solder paste, the processing mode of two classes for a long time; 24 hours non-stop high-speed operation.

For this matter, you can only find a solder paste factory to make the modulation; take out the solder paste from the refrigerator, you can also quickly carry out production operations. In addition, solder paste does not partition the tin powder model, whether it is a BGA chip, or only a large piece of more than 1206, only a solder paste.


In addition, it is the tin wire. The tin wire we use is the same as the color of the mounted components. The hands of the tinsmith, even if they took a day's tin wire, there would be no rosin splash on the hand, because the standard 63/37 tin wire was used.

Third, the operating tools and working environment, the tools used here only use Aetna's air gun, and the new Rieter's soldering station, as well as a professional preheating station, heating station, BGA chip rework station. Zui guarantees the stability and reliability of welding to a large extent.

The entire workshop is closed and fully air conditioned. The temperature and humidity of the entire production process are guaranteed to have a direct impact on the welding of the product.

Therefore, we have always described the orders that we have received: to make orders that the big factories are not willing to do, and to make orders for small factories.


There are many factories for PCB surface mount, but there are very few professional small batches. There are very few types of processing plants of this type that can be hand-applied, machine-made, precision, quality, and substitute.

With the rise of smart wear and the Internet of Things, the early stage of research and development, production, and small batches all require a batch of processing plants that can engage in lean production and fine processing. I believe that I can do this well, and I hope that I can catch up with the Internet + wave. Contribute yourself to this power!

Since PCB surface mount processing plants are numerous, especially in Shenzhen, China. Everyone knows that Shenzhen's electronics and electrical appliances are world famous. Many medium and large companies have quietly launched the PCB surface mount production line in order to meet the needs of the products. How do you choose a trusted supplier in many PCB surface mount processing plants?


1

See the Concept of Cooperation

As a part of the whole electronic product manufacturing process, PCB surface mount processing, when the equipment is highly developed and the management is perfect, the professional fit of the PCB surface mount processing factory seems to determine whether your PCB board can be delivered on time. Whether the quality can be controlled and whether it can be repaired in time, these added value is much higher than the unit price difference between 9% and 1 gross. How to investigate the degree of cooperation of PCB surface mount processing plants? Start with people. Talk to the management and even the boss of the PCB surface mount processing factory to see if they have a sincere attitude and belief. In addition, you can also learn about the reputation of the processing plant and the customer cases that have been served through third parties.

Look at the quality management process (Quality Control)

Many PCB surface mount processing plants are struggling to reduce the unit price in the market, at the expense of quality, reducing QC personnel or not equipped with AOI for testing. In the process of evaluating the PCB surface mount processing plant, it is necessary to observe in detail and understand whether the IQC, post-inspection, QC and other series of positions in the warehouse are set, whether the AOI testing equipment is equipped properly, whether it is opened, and the quality of the engineers. The introduction of management methods and documentation, etc., can only ensure that your products are processed perfectly if you have a comprehensive understanding.

3

See the management and staff's mental outlook (Work Passion)

The mental outlook of frontline employees and managers determines whether your products can maintain high yields, consistency, etc., because the products are made by people or operating equipment. Whether the communication with the manager is smooth, whether it is passionate, whether the employees are meticulous in their work, and each has their own duties.

Give up these useless reviews (Give Up These Audits)

1, look at the size of the factory: unless your order is enough 100k, any PCB surface mount processing plant can do it

2, look at the PCB surface mount equipment: Unless the PCB board has very small materials (such as 0201 and below) or complex processes (POP, etc.), the general factory PCB surface mount equipment can do

3, look at the quotation: the first quotation is a little outrageous point, it negates a PCB surface mount processing plant, it is possible to deny that a very good one. Everything that dares to speak is capable. If there is a requirement for quality, the initial offer can only be referenced, or even refer to it.

4, look at the chest: only rely on the PCB surface mount processing factory's commitment to the chest, or chat, sensibly chose this supplier, which is very risky.

Good companies have long-term stable PCB surface mount processing plants, and poor companies are constantly looking for and repeating yesterday's story. Therefore, the choice of PCB surface mount factory needs to pay attention to these several conditions, everyone to polish their eyes to identify, can not save for the sake of the map, just find a family, the results are not good enough to lose!
