Production PCB assembly fixtures (also known as SMT fixtures even though they can also be used for through hole applications) are the traditional fixtures made with a heavy-duty (Electro-Static Discharge) ESD composite, pressed fibre, thermoset plastic which offers extreme strength and excellent electrical and thermal properties. It comes in black and gray. Production fixtures last a long time, but they are expensive and could take several days to fabricate.

Prototype PCB assembly fixtures are specially designed for prototype and short run PCB projects. They are made with high Tg FR4 material or stainless Steel. High Tg FR4 is the fiber glass heat resistance, moisture resistance and chemical resistance material that is used to fabricate printed circuit boards. Stainless steel SMT fixtures are laser cut with the same kind of infrared lasers used to manufacture SMT stencils. High Tg FR4 and thermoset plastic fixtures are made with CNC machines.

Surface Mount Carriers

Surface mount carriers are extremely versatile. They can be used to support, protect and transport PCBs of different sizes and shapes including flex and rigid-flex PCBs through the SMT process. Surface mount carriers can significantly decrease setup time and improve handling.
Stainless steel fixtures can be used during the printing and placement process. They cannot be used for the reflow process.

Wave Solder Pallets

Wave soldering is still widely used in printed circuit board manufacturing for soldering through-hole components. Wave solder pallets are used during wave soldering to mask SMT components (ground planes, gold fingers and mounting holes) while exposing the circuit board to the wave only where solder is required. Our wave solder pallets are custom designed to meet your project requirements.

Selective Solder Fixtures

Selective soldering is the preferred method of soldering through-hole components on a mixed technology assembly. Selective solder fixtures are used during selective soldering to protect SMT components and to shield thermally sensitive parts from the heat and solder.
Stainless steel fixtures are not be used to fabricate selective solder fixtures.
