PCBA is processed through the SMT machine process, it is also a kind of components, then the thickness of PCBA, baking temperature of knowledge, and today to tell you.
Board thickness, is based on different industry product differences, some boards are thin, some boards are thick.
PCBA board is divided into soft board and hard board, soft board is FPC, mostly used to connect the circuit board, hard board and divided into a single panel, double-layer board, multi-layer board, the thickness of the board is usually 1.6mm thick, the greater the frequency of the circuit, the greater the thickness will be.
PCBA baking temperature, generally in the range of about 100 + 20 degrees. pcba is basically no need to bake, mainly pcb baking before the patch, for the following reasons
pcb placed for a long time, subject to environmental moisture attached to the surface, some boards will adsorb water vapor to the internal
pcb board exposed to the normal environment, subject to oxidation
affected by water vapor and oxidation, some boards warp
Therefore, pcb needs to be baked before processing in processing, especially the kind of open and unused, poor storage environment of the board, must be baked for more than 30 minutes before use.
If not baked, it may cause burst board when reflow welding, and placement is not accurate, occur empty welding, standing monument and other bad quality.
The above is about pcba thickness, baking temperature some aspects of the explanation, I hope it can help you.
