Surface Mount Pallets

Successful SMT circuit carrier implementation is relevant to the circuit design or array layout. Stone Mountain Tool is happy to review design layout early in the circuit development process to enhance successful manufacturing processes.

Flexible and Rigid Flex circuits bring with them unique problems which by their very nature require unique solutions. We have found several ways to overcome these problems which sometimes not only helps retain it in place but also aides in keeping it flat as well.

The use of PCB tension, compression, collapsing locating pins, multiple hold downs, tac-strips, spacers, and cantilever hold downs are some of the ways to help you present your flex/rigid-flex to your process providing precise X-Y location, and positive clamping on a stable platform for print, place and reflow.

Exclusive “Push Away Tooling Pins” are used to locate the PCB. The use of the vacuum from your machine can be transferred through the pallet “TO” keep the substrate on the fixture. Clamping the flex circuit for pick & place and reflow may be done with the use of a variety of different clamp designs.

The clamps can be engaged manually or automatically post screen-print on the exit rails of the printer. The circuit is precisely located and positively secured to a precise flat surface during the surface mount technology manufacturing process with pallets designed by Stone Mountain Tool.
