First, the principle of patch proofing
Patch proofing refers to the chip is fixed on the printed circuit board using welding technology, welding the foot on the chip and circuit board line, connect the line, complete the circuit connection, so as to achieve the purpose of proofing a technology. The principle of patch proofing is very simple. First, the chip is removed from the package, and then the chip is fixed on the printed circuit board. Then, the feet on the chip and the circuit board are connected by welding technology.
Two, patch proofing materials
The required materials for patch proofing are printed circuit boards, chips, solder and welding equipment. The printed circuit board is used to mount the chip, which is the core component of the control circuit, and the solder and welding equipment are the tools used to connect the foot of the chip to the circuit board wiring.
Three, the steps of patch proofing
1. Positioning step: Take the chip out of the package, fix it on the printed circuit board, and connect the foot of the chip to the circuit board.
2. Welding steps: Use welding equipment to connect the foot of the chip to the circuit board. After welding, use a detector to test the sample to ensure the correctness of the patch proofing.
3. Cleaning steps: Clean the finished patch proofing with an automatic cleaning machine to ensure the cleanliness of its surface and remove the welding residue.
Iv. Precautions for patch proofing
1. Position the circuit board accurately to ensure that the chip foot and circuit board line can be effectively connected.
2. Welding should be skilled, and to ensure that the welding connection is firm and clean.
3. Clean the patch proofing thoroughly to ensure its surface cleanliness, otherwise it may affect the quality of the patch proofing.
Five, the advantages of patch proofing
1. The quality of the patch proofing is reliable, which can ensure the effective connection between the chip foot and the circuit board and ensure the normal operation of the circuit.
2. Patch proofing can meet the requirements of various specifications, such as different chip packaging, chip parameters, so as to better meet the needs of customers.
3. Patch proofing can effectively improve production efficiency, reduce production costs and improve the competitiveness of enterprises.
Six, the application of patch proofing
Patch proofing technology is widely used in the production of various electronic products, such as household appliances, Automotive electronics, computer peripheral products, mobile phones and so on. Because of the reliable quality of the patch proofing, can effectively reduce the production cost, so it is widely used in the production of various electronic products.
