For the time being, the testing methods in this industry mainly include: production test racks (sub-composite and special-purpose), flying probe test, and AOI test. The cost of testing is mainly about equipment selection and materials.
1.The relationship between equipment selection and cost control. Different manufacturers have different order structures, and the order structure largely restricts equipment selection.The relationship between equipment selection and cost control.

2. The biggest advantage of the flying probe is that the market response speed is fast and the cost is extremely low, but the detection speed is slow. Generally, it takes three to ten minutes to test a shipping unit, which is suitable for test samples and small orders. If the customer requests to take a sample, the flying probe test can be selected until the customer changes to the fixture test when they have larger orders, thus eliminating the cost if customer change process or canceling fixture production.
3.Save costs from designing test and process strategies. When designing a test method and process strategy, we must consider a myriad of variables. In this case, we should choose different test methods and production methods according to different situations. The cost of a high-density pcb test fixture and a common pcb test fixture is very different (depending on the probe size and points). The average cost hundreds yuan, while the common high density requires thousands. At this time, it is conceivable to use conductive strips instead of expensive small probes.
According to above, the cost of rational test process technology in cost control is amazing. Shenzhen Baiqiancheng always help customers save the cost.
