There are many PCB manufacturers, Dongguan Huaqiang has done a good job quickly, delivery time and production quality problems can be, they have their own business documentary personnel, customers can answer any questions promptly, this is the most critical, anyway, the after-sales service of each company is different, depending on the person. Now it is more and more convenient to search information on the Internet, but more and more advertisements will make people feel a little cloudy. Which brand of PCB board is better? Let's take a look at the details.
Nowadays, the major PCB proofing manufacturers have relatively mature models in terms of quality and price, but delivery and shopping experience are two levels that many consumers value more recently. Let's take the PCB circuit board as an example to illustrate:
The delivery is fast.
If your PCB production needs are not so urgent, then you can find relevant PCB factories in the market to buy the general production needs, but to make a fast board, many manufacturers will involve a "fast fee" statement, how to spend less money, faster access to the board, is a lot of consumers need to find. The reason for going to a good brand.
Good service?
Nowadays, most PCB PCB purchasing tends to online purchasing. Without face-to-face communication, merchants will increase the stickiness of customers and manufacturers through complete and high-quality customer service. Just like JSP owns the whole process of documentary customer service, only letting customers know where their list is at the moment and whether they can contact the end of the problem at the first time will bring better consumer experience to the purchaser.
PCB processing is the most basic link, there is no PCB behind everything can not be talked about, there is no qualified PCB behind all the processes are white-collar, so in the electronic processing industry, every detail needs our attention and serious treatment. Then, after the PCB circuit board is finished, the quality inspection of PCB is indispensable. So how to test the quality of PCB board is the key point to be elaborated in this article.
First of all, the most is that the appearance of PCB can be roughly distinguished from the general experience. Usually, the appearance of PCB can be analyzed and judged from three aspects:
1. Standard rules for size and thickness.
PCB boards have different thickness to standard PCB boards. Customers can measure and check PCB boards according to the thickness and specifications of their products.
2. Weld appearance.
Because PCB boards have many parts, if the welding is not good, the parts are easy to fall off the boards, seriously affecting the welding quality of the boards, good appearance, careful identification, a strong interface is very important.
3, light and color.
External PCB circuit boards are covered with ink, circuit boards can play an insulating role, if the color of the board is not bright, less ink, insulation board itself is not good. In fact, the performance of PCB boards depends on the material used (high Q value), wiring design and several layers of boards. However, in the process of washing PCB, black is the most prone to cause color difference. If the raw materials and manufacturing process used in PCB factory are slightly deviated, the color difference will cause an increase in the rate of poor PCB. This directly leads to an increase in production costs.
Because the circuit routing of black PCB is difficult to identify, it will increase the difficulty of maintenance and debugging in R&D and after-sales stage. Generally, black PCB will not be used easily without the brand of RD (R&D) designers and powerful maintenance team. It can be said that the use of black PCB board is a brand's confidence in RD design and post-maintenance team performance, but also the performance of strength.
Generally speaking, if you want to find a good PCB manufacturer, you have to use various factors to measure comprehensively. Don't be partial, easily fall into the trap set by the merchants, causing irreparable losses.
