Selective Soldering
Selective Soldering
Selective Soldering is a precise and cost effective way to solder through-hole technology. It uses flux and mini wave technology to apply a precise amount of flux and solder to select through hole components termination on a printed circuit board(PCB) .
Selective soldering acts on the underside of the board without affecting anything on the top. A board is positioned in a frame, and all subsequent operations occur automatically according to the process control system programmed in advance for that board.
Its process soldering process includes:
- All selective areas are fluxed first
- All areas are then preheated to activate the flux
- Each joint is soldered one at a time according to the program
selective soldering allows a manufacturer to solder through-hole pins and work around delicate SMT packages by targeting specific areas on the board. This promotes repeatability – and therefore fewer defects, increased throughput, and overall cost reduction.
