Why does the processing of Shenzhen DIP plug-in appear false welding
At present, the country has higher and higher requirements for environmental protection and greater efforts in link governance. This is a challenge but also an opportunity for PCB factories. If PCB factories are determined to solve the problem of environmental pollution, then FPC flexible circuit board products can be at the forefront of the market, and PCB factories can get opportunities for further development.
The Internet era has broken the traditional marketing model, and a large number of resources have been gathered together to the greatest extent through the Internet, which has also accelerated the development speed of FPC flexible circuit boards, and then as the development speed accelerates, environmental problems will continue to appear in PCB factories. In front of him. However, with the development of the Internet, environmental protection and environmental informatization have also been developed by leaps and bounds. Environmental information data centers and green electronic procurement are gradually being applied to the actual production and operation fields. From this point of view, the environmental protection problems of PCB factories can be solved from the following two points.
After processing the Shenzhen DIP plug-in, wave soldering and manual soldering are required to fix the components on the PCB board. What are the main reasons for the virtual soldering during wave soldering?
Possible Causes:
1. The surface of the PCB board is not clean, the surface is oxidized or is contaminated by dirt, grease, hand sweat, etc., resulting in poor solderability or even unsoldering of the surface;

2. The solderability of circuit boards (PCB boards) and components purchased by the purchasing department are unqualified, and strict acceptance tests have not been carried out before entering the warehouse;

3. Poor inventory environment (the temperature, humidity and other external factors that the warehouse should keep are inappropriate), and the inventory period is too long;

4. Due to the wave soldering furnace itself, the temperature in the soldering furnace is too high, which leads to accelerated oxidation of the surface of the solder and the base metal, which reduces the adhesion of the surface to the liquid solder. Moreover, the high temperature also corrodes the rough surface of the base material, which reduces the capillary action and deteriorates the flowability.

Measures to prevent false welding in Shenzhen DIP plug-in:
1. In terms of procurement, we must strictly check the purchased PCB boards and components to ensure their solderability.

2. To improve the warehouse environment, maintain proper temperature, humidity and no corrosive gases.

3. The PCB board and components must ensure the principle of first-in, first-out, to avoid quality problems of some components due to storage for too long.

4. The operator should take anti-static measures to keep it clean when carrying out the DIP plug-in. iPCB is happy to be your business partner.
