/How does the Pcba factory better disassemble components?
Second, for the components of the pcba factory with more components and pins, the patch components with wider spacing are similarly applied. First, tin is plated on one of the pads, and then the left hand is soldered with a pair of tweezers. Then solder the remaining feet with tin wire. The disassembly of such components is generally better with a heat gun, a hand-held hot air gun blows the solder, and the other hand removes the component with a clamp such as a tweezers.
Third, for components with high pin density, the soldering step is similar, that is, solder one foot first, then solder the remaining feet with tin wire. The number of pins is relatively large and dense, and pin-to-pad alignment is critical. Usually the pads are selected on the corners, only a small amount of tin is plated, the components are aligned with the pads with tweezers or hands, the sides of the pins are aligned, the components are pressed on the PCB with a little force, and the solder is soldered with a soldering iron. The corresponding pins of the disk are soldered. Instead of shaking the board vigorously, turn it gently and solder the pins on the remaining corners first. When all four corners are soldered, the components will not move at all, and the remaining pins will be soldered one by one. Apply some loose perfume first when welding, a small amount of tin on the tip, and one pin at a time.
Finally, it is recommended that the high-pin-density components be disassembled mainly with a heat gun, clamp the components with tweezers, blow all the pins back and forth with a heat gun, and lift the components when they are melted. If the removed component is still needed, then try not to face the center of the component when blowing, and the time should be as short as possible. After removing the components, clean the pads with a soldering iron.
The above is the desoldering technique of the pcba factory. FASTPCBA Technology will also continue to improve quality and provide customers with high quality PCBA manufacturing services.

In PCB printing manufacturing, the production craft is an extremely important link. Generally, the pcb craft has osp, immersion gold, gold plating, spray tin and so on. Among them, spray tin is the most common craft in PCB production. Everyone is familiar with it. In the tin-spraying craft, it is...
When most pcb manufacturers carry out PCB welding board turnover in the workshop, due to the heavier pcb board, when the components are soldered by hand, the improper movement operation will cause the components on the PCB board to fall off and the probability of collision will be very high. So h...
