SMD varistors (SMD resistor) name fixed chip resistors, chip varistor is from chip fixed resistor direct translation, which is characterized in that the moisture resistant, high temperature resistant, reliability is high, the appearance is uniform in size, precise, and temperature coefficient of resistance tolerance.
Production process of patch based pressure sensitive resistor
Basic steps of the patch:
SMT process mainly has three basic operation steps: coating, coating, welding.
Coating for coating
- coating is solder paste (or adhesive coating) to the PCB board. Coating related equipment: printing machine, point paste machine.
Coating related equipment is printing machine, point paste machine.
Patch pressure sensitive resistor
- paste the SMD device is attached to the PCB board.
Reflow solder paste:
- reflow is the component in the melting and heating, solder paste solder to devices and electrical connection between PCB.
Related equipment: reflow soldering furnace.
