Question: What is a PCB Stencil?

Answer: A PCB Stencil is a sheet of stainless steel with laser-cut openings used to place solder paste on a PCB board for surface mount component placement. The PCB stencil is used to deposit solder paste on designated places on a bare PCB board so that components can be placed and perfectly aligned on the board.

Its main function is to accurately deposit the right amount of solder paste on SMT pads so that the solder joint between the pad and the component is perfect in terms of the electrical connection and mechanical strength.

Using a PCB Stencil to apply solder paste makes the PCB Assembly process faster. It also makes it easier to apply solder paste accurately.

PCB Stencils are manufactured by creating openings through lasers on a stainless steel foil based sheet at the positions where Surface Mount components need to be placed on a board. The stencil is then placed on the top of the PCB and aligned perfectly using positioning points called fiducial marks. After alignment, the solder paste is applied with a metal squeegee blade. As a result of this, the solder paste gets placed on the PCB board where the surface mount components need to be placed. So when the stencil is removed, components can be placed on the board.

Witgain Technology Ltd was established in 2007 in ShenZhen City. After over 10 years development, the company now posses two factories. One factory located in HuiZhou City which is near to ShenZhen. The other one locates in JiangXi Province. Marketing dept still locates in ShenZhen City.

We have about 300 employees in two factories and the monthly output is around 30000m2. Our marketing orientation is to make high difficult and special treatment pcb. Even though, we still accept normal 2-layer and multi-layer pcb orders. Our products cover simple double layer pcb, multi-layer pcb, HDI pcb, rigid-flex pcb, fpc, ceramic pcb, heavy gold/copper pcb etc. Wide product ranges and flexible order quantities allow us to satisfy most customer's demands. 

Quality and technology is what we value most and we will never stop improving our capabilities. Our customer's satisfication is always what we are seeking for.
