How to select PCBA factory?
When choosing PCBA plants, many customers are confused because they are not very professional. It is unreasonable to judge the capacity of these plants by their size alone. So how do we choose PCBA plants? At this point, we listed the aspects to be examined in selecting PCBA plants.
First, to check whether the environmental impact assessment is qualified, we need to check the EIA certificate and the relevant EIA certification invoice.
Second, check the quality management system certificate should have ISO9001 and ISO12345 these two certificates;
Third, provide the original factory and core agents of the procurement contract samples, to ensure that all raw materials are from the official channels of authentic products, to avoid second-hand materials and defective materials mixed into product production;
Fourth, check the IQC incoming inspection, check the IQC incoming record, whether can live through the color and the label to distinguish good/bad product, the purpose is to avoid bulk composition error, bias, deformation or unqualified material attached to the PCBA, cannot detect and covered in the testing stage, bring the product potential hidden trouble, influence the stability, short service life;
Fourth, check the IQC incoming inspection, check the IQC incoming record, whether can live through the color and the label to distinguish good/bad product, the purpose is to avoid bulk composition error, bias, deformation or unqualified material attached to the PCBA, cannot detect and covered in the testing stage, bring the product potential hidden trouble, influence the stability, short service life;
Fifth, look at the raw material storage environment, must have a professional electronic material warehouse, constant temperature 22-28℃, humidity 40-70%; Sensitive components must be stored in a damp proof cabinet and assembly disassembly and recovery must be kept in a detailed ledger;
Sixth, electrostatic protection, all electronic component racks and PCBA product racks must use independent static wire connection, employees must wear rope electrostatic ring and electrostatic alarm, must have daily electrostatic spot inspection records;
Seventh, PCBA factory shall be equipped with three anti-paint spraying production lines.
Eighth, looking at engineering skills, PCBA plants must have the ability to analyze and solve defective PCBA boards to ensure that root causes are found, rapid delivery and release the energy of customer engineers rather than leaving all problems to customer engineers.
Finally, look at the management level of the site, the operation site can reflect the comprehensive implementation ability and level of the factory. There is no stackable PCBA, Wuxi beads and tin slag on the workbench, and no splashing at the cutting Angle.
Of course, we are not limited to these contents for selecting PCBA factories. Depending on how much time we have available, choose something that only takes half a day to read, or one or two days to audit.
