BEST Inc. has developed a simpler process for reworking or hand-placing high lead count connectors. The BEST StencilQuik™ polyimide stay-in-place stencil helps rework high-density connectors by preventing bridging of neighboring solder joints while allowing technicians to “fit” connector contacts into the stencil.

The process of placing or reworking the connector has been greatly simplified. After preparing the site, the StencilQuik™ stencil is peeled from its release liner. It is then aligned on the circuit board. Solder paste is then squeegeed into the apertures of the stencil with the remaining material wiped away with a lint-free cloth. The connector is ‘fitted’ into the loaded apertures and then reflowed. In addition to simplifying the process any mask damage ensuing from device removal is repaired by placing the device onto the board. www.solder.net
