The clamps or shelves used for testing are called test stands;There are two types of product improvement tests.First, the purpose of PCB product innovation and improvement in features is to capture more market share. Here, the goal of PCB product testing is to determine whether the improved product is really better than the improved one.The second is cost reduction improvements.The purpose of product testing here is to determine whether the customer can distinguish between the improved product and the improved product.It can also be used for repair circuit board detection.
The circuit boards manufactured by FASTPCBA can be repaired free of charge within one year, only for abnormal circuit boards.
1.Lift test stand wrench up
2.Put the board to be measured into the slot
3. Press down the spanner
When PCB is carrying out SMT chip processing (SMT), there are usually 3 methods (based on the situation of opening the steel mesh): all manual, semi-automatic, and fully automatic. All manual is to brush the steel mesh, and the electronic components are placed manually. Semi-automatic refers to b...
, and connect them to complete specific functions of the circuit. Compared with discrete component circuits, integrated circuits greatly reduce the volume, weight, number of lead wires and solder joints of point circuits, and improve circuit performance and reliability. The miniaturization, minia...
PCB circuit board proofing or board making requires a lot of information, and the difference in each item will have a huge impact on the final price. Size, board thickness, surface treatment, resistance resistance, solder mask coverage, solder mask color, gold finger, copper foil thickness, etc. ...
