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. Single-sided mounting process Single-sided mounting means that the components are all mounted components, and the components are assembled on one side of the PCB. The main process of single-sided placement process: printing solder paste → patch → reflow soldering → cleaning → detection → rewor...
The printed circuit board adhesive is also a pcb assembled red plastic, usually a red (also yellow or white) paste uniformly distributed with a hardener, a pigment, a solvent, etc., mainly used for the patch processing element. The device is attached to a printed board and is typically dispensed ...
The miniaturization, light weight and diversification of functions in the electronic field are the driving force and source of SMB development. Typical examples are mobile phones. Technology is pushing SMB manufacturing technology to the following direction: (1) High precision of pcb assembly. (2...
