2020-05-20

1. The professional level of the factory


PCB assembly processing is a very complicated step. From PCB manufacturing to assembly machine and software, each department must cooperate and cooperate with each other. Whether the factory has the overall strength of commodities, the professional level is especially critical.




1.1 Is there a professional machine or equipment?

PCBA processing and manufacturing must be very professional machinery and equipment, such as high-speed mounting equipment, multi-temperature zone reflow soldering furnace, ICT online tester, AOI detector and other machinery and equipment, all of which are basic to ensure manufacturing.


1.2 Is there a professional process optimization

In addition to professional production line equipment, PCBA proofing requires a systematic management method to conduct professional supervision on quality. The better circuit board business manufacturers have all passed the verification of ISO9001 quality system management, IAF, IPC-A-610E electronic device assembly and acceptance standards, and will undergo specific guidance on the individual behavior of employees through material documents such as SOP position safety operation regulations. According to the query of the factory's material text documents and professional qualification certification, it can roughly grasp the overall strength of the factory's quality supervision.


1.3 Is there a sound testing process?

In addition to professional machinery and equipment, professional process optimization must also have a sound testing process. Everyone knows that proofing is a meticulous job. The mounting of many electronic components, DIP and even software welding with many pins, the whole process is complicated and the quality will be difficult. Therefore, it is necessary to strictly check each layer, severely crack down on quality shortcomings, and "find leaks and fill gaps". A PCBA proofing company that pays attention to quality will configure detailed inspection process: IQC finished product inspection, SPI solder paste inspection, online AOI inspection, SMT first sample inspection, appearance inspection, X-ray welding inspection, BGA yuan Device maintenance, QA testing, anti-static in and out storage


2. Responsibility


A PCBA manufacturer with a good sense of responsibility can actively and responsibly deal with difficulties for customers when they encounter difficulties. PCBA proofing manufacturers bring processing business, not a real commodity. Therefore, the responsibility awareness of a PCBA proofing manufacturer is very important. The PCBA proofing manufacturer's sense of responsibility can grasp the company's corporate culture according to its official website and its marketing staff's mentality of customers.

3. Working experience in manufacturing industry


Nowadays, the PCBA manufacturing industry is in the water dream. Some poorly operated PCBA proofing manufacturers have gone bankrupt and closed down. PCBA manufacturers with many years of experience in the manufacturing industry have strong overall strength and more business. advantage.


4. Price


In the sales market, the price of PCBA proofing is relatively transparent. There are higher prices and lower prices, but the lower the price, the better. Some PCBA proofing manufacturers choose to purchase genuine products, original well-known brands of electronic devices, and implement strict quality supervision, which increases the cost of processing; and some PCBA manufacturers in order to reduce prices will Good charging results in unstable quality, poor delivery quality, and many defective products. people should choose suitable and cost-effective PCBA manufacturers according to their own conditions
