First, look at the proofing requirements. Can PCBA processing manufacturers really meet:
1. Have a look at the products manufactured by PCBA manufacturers, whether they are high-grade, middle-grade or low-end, which industry they manufacture, and whether their own PCBA proofing requirements can be met by the manufacturers.
Some precision processing PCBA processing, general proofing enterprises are limited by technical working ability and machinery and equipment, so they can’t bring this kind of business.
2. If the manufacturer can bring it, it also depends on whether the delivery time of the manufacturer is fast enough!
Many PCBA proofing requirements pay great attention to the short delivery time, and the faster the goods can be landed on the floor. Many enterprises can’t deal with the crisis of delivery time. When I speak fast, I mean 24-hour delivery. In urgent cases, the delivery time can be shortened to 8 hours.
3. There are also some batch production order information. Whether PCBA processing factory is a difficult problem to contract.
The basic requirements have been considered, so let’s take a look at the following key points;
Second, the professional level of the factory
PCBA processing is a very complicated step, from PCB proofing to post-patch, software, etc., which must be coordinated by each department. Whether the factory has the overall strength of commodity processing, especially the professional level is the key.
1. Is there any professional machinery and equipment?
PCBA processing and manufacturing must be very professional machinery and equipment, such as high-speed mounting and pasting machinery and equipment, multi-temperature zone reflow oven, ICT online tester, AOI tester and other machinery and equipment, all of which are the basics to ensure manufacturing.
2. Is there professional process optimization?
Besides professional production line equipment, PCBA proofing requires systematic management methods to carry out professional supervision on quality. Good PCB manufacturers have been verified by ISO9001 quality system management, IAF, IPC-A-610E electronic device assembly acceptance standard, etc., and will give specific guidance to employees’ personal behavior through SOP post safety operation procedures and other materials and documents. According to the materials, documents and professional qualification certification of the factory, we can grasp the overall strength of factory quality supervision.
3. Is there a sound testing process?
In addition to professional machinery and equipment, professional process optimization, but also have a sound testing process. Everyone knows that proofing is a meticulous work, and the mounting and pasting of many electronic components, DIP and even software electric welding with many pins, the whole process is complicated, and the quality will be difficult. Therefore, it is necessary to strictly check the quality defects layer by layer, and to “check for leaks and fill vacancies”. A PCBA proofing enterprise that pays attention to quality will be equipped with 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 component maintenance, QA inspection, antistatic in and out of the warehouse.
Third, the sense of responsibility
A PCBA proofing factory with a good sense of responsibility can deal with difficulties for customers actively and responsibly when they encounter difficulties. The processing business brought by PCBA proofing manufacturers is not a real commodity. Therefore, the sense of responsibility of a PCBA proofing manufacturer is very critical. PCBA proofing manufacturers have a sense of responsibility, and can grasp the corporate culture of the enterprise and the mentality of its marketing staff towards customers according to its official website.
IV. Working experience in manufacturing industry
Nowadays, the PCBA manufacturing industry is in the water dream, and some poorly managed PCBA proofing manufacturers have gone bankrupt one after another. However, PCBA manufacturers with many years of working experience in the manufacturing industry have strong overall strength and more advantages in business.
V. Price
In the sales market, the price relativity of PCBA proofing is completely transparent, and there are high prices and low prices, but the lower the price, the better. Some PCBA proofing manufacturers choose genuine and original well-known brand electronic devices, and implement strict quality supervision, all of which increase the processing cost; In order to reduce the price, some PCBA proofing manufacturers will be shoddy, resulting in unstable quality, poor delivery quality and many defective products. As the saying goes, you get what you pay for, people should choose suitable PCBA proofing manufacturers with high cost performance according to their own conditions.
