How to deal with poorly processed PCBA products
The Internet era has broken the traditional marketing model, and a large number of resources have been gathered together to the greatest extent through the Internet, which has also accelerated the development speed of FPC flexible circuit boards, and then as the development speed accelerates, environmental problems will continue to appear in PCB factories. In front of him. However, with the development of the Internet, environmental protection and environmental informatization have also been developed by leaps and bounds. Environmental information data centers and green electronic procurement are gradually being applied to the actual production and operation fields.
First, eliminate human factors. If it is a machine that has not been dismantled, you can perform visual inspection and functional testing first. To confirm that the product is really defective. Before getting the defective product, ask the customer under what circumstances the defective product occurred, so that you can grasp the situation and determine the cause of the defective product. Some products returned by customers are sometimes misjudged as good ones. There may be no problems with the product itself. It may be caused by some customers’ power supply problems or other operational problems, which has nothing to do with the product itself. Check the appearance carefully to see if there are any signs of drop and impact. Some of the defects are caused by damage to internal parts due to impact. Some undesirable phenomena will only appear after the machine is turned on for a period of time, and some will appear intermittently. The best way is to turn on the machine and let the automatic program run for a day and then take a look and do some basic operations to see if the problem can be reproduced.

Secondly, if it is disassembled, it must be dealt with. Some repaired products may be caused by short circuits caused by foreign objects (caused by insects such as cockroaches or spiders, or liquid contamination), and some defective products may also cause short circuits and burn parts or circuits due to some reasons. It can be roughly seen from the appearance. PCBA processing companies can use microscopes to inspect the condition of the circuits and parts on the circuit board, and do a carpet inspection without letting go of any clues.
Finally, the circuit board is tested for electrical properties, and the temperature of the chip IC is measured at the same time. If the customer only returns the circuit board, it is necessary to conduct an electrical test on the circuit board after the appearance inspection. Even if the customer returns the whole machine, they can also do electrical tests on individual circuit boards to determine which PCBA has the problem. If the machine may be composed of several boards, the elimination method should be used. Preliminary exclusion can be done. Speed up the discovery of the problem and solve it. Over the years, we are proud to maintain a 99% on-time delivery rate. We work in three shifts to ensure that your PCB can appear on your desk as planned and as early as possible. You can choose DHL and other courier services to balance speed and budget. We only use services from reliable and reputable companies.
24 hours customer service
Whenever you encounter any problems, you can contact the on-site customer service staff to reply to your emails or messages. From the moment you submit the Gerber file to the moment you receive the PCB and the assembled PCB, our service staff will follow up your order with satisfaction.
Customer complaints and refunds
iPCB attaches great importance to customer satisfaction, so we have established a responsible customer complaint department. If you are dissatisfied with our products after receiving our products, you can ask us to refund to your iPCB credit account, or request to re-produce the failed order. Of course, if you are still dissatisfied with our service or have any suggestions, you can send an email to us so that we can spend more time improving the service and establishing a complete suggestion system to satisfy our customers and ensure their interests.
