FASTPCBA has the world’s advanced precision PCB patch machine and testing equipment, providing our customers with a steady stream of high-quality products.
Electrification test: the information such as voltage, waveform and frequency is tested.And these are the conditions that determine whether the circuit is working properly.
Test requirements: test fixtures (multimeter) Functional test: verify each function of the product. Test item by item according to the functional test cases to check whether the product meets the function required by the customer.
Test requirements: the customer provides test steps and functionality to be validated, along with job guidance.
Other tests: PCB plate test/component performance test General test instruments and equipment are available from the factory.For special testing of customers’ products, customers need to provide their own testing instruments and equipment.
Tip: as long as the Gerber file and bom file provided by the customer normal or the product design normal .99.98% of the products are normal, but do not rule out individual functional abnormalities.If the customer requests a test, a test fee will be charged.
1.Snpb Hot Air Leveling craft. The Snpb Hot Air Leveling craft is a traditional PCB pad coating method. The specific craft process is immersed in the molten Snpb alloy after the PCB circuit is etched, and then slowly lifted and coated with a Snpb alloy layer under the action of hot air, which is ...
The width of the printed conductor depends on the current carrying capacity of the conductor and the allowable temperature rise. The thickness of the copper foil plated copper foil is generally 0.02 to 0.05 mm. The different widths printed conductors have different cross-sectional areas too. The ...
After the position and shape of the components on the PCB board are determined, the wiring can be performed according to the position of the components. The following are the basic requirements for the circuit board: The low frequency wires are placed close to the edge of the printed circuit boar...
