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
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...
