What Is the Purpose of Baking PCBs Before Production in SMT Processing Factories?

2026-04-13

Anyone who has worked in an SMT processing factory knows that PCBs are generally baked in an oven before surface mount technology (SMT) processing (except for special substrate materials). The primary purpose of this process is to remove moisture and dampness.

How Stencils Affect the Quality of SMT Assembly Processing

2026-04-11

Those engaged in SMT assembly processing all know that stencils are used in the first process of PCBA assembly processing. The function of a stencil is to print solder paste onto the corresponding pads of the circuit board through the openings of the stencil by screen printing.

What is three-proof adhesive for PCB? Three-proof adhesive for PCB, also known as three-proof adhesive for circuit board or coating adhesive, is a kind of coating adhesive with special formula, which is used to protect printed circuit board (PCB) and its related equipment from environmental factors. It can form a protective film on the surface of PCB, which has many protective functions,

What are the main cleaning processes of SMT solder paste Stencil?

2026-03-13

The main function of SMT solder paste steel mesh is to help solder paste to be printed on PCB pads accurately. In this process, it is inevitable that some solder paste will remain. Generally, the SMT steel mesh needs to be cleaned after use, so as to prevent the solder paste remaining on the steel mesh from affecting the secondary use. In order to achieve a good cleaning effect and control the cost, it is necessary to choose a suitable cleaning process and cleaning agent.
