The Old Way
PCB Unlimited manufactures the universal stencil fixtures in our state-of-the-art facility in Tualatin, Oregon. Our universal stencil fixtures are made to last. They are manufactured with heavy-duty (Electro-Static Discharge) ESD composite materials such as Durostone® and Ricocel.The universal stencil fixture was cleverly designed to provide the following benefits:
The board fixture contains rubber feet on the bottom side to enable double side printing and prevent the fixture from moving during the print process. It also contains fixed and sliding bars as well as PCB holders to provide universal board support. The fixed and sliding bars have a grid to help position the board on the fixture.
The registration fixture can be rotated or moved vertically and/or horizontally to achieve perfect registration. It comes with powerful magnets to keep the fixture from moving during the printing process.
The stencil fixture has a couple of pullers on the bottom side to provide stencil tension. There are four levers on stencil to enable vertical lift thus avoiding the smearing of the solder paste on the PCB. The handles on the top side are used to remove the stencil fixture and replace the PCB.
