TEST ELECTRONICS’ PROCESS CARRIER PALLETS
Titanium for Wave Solder Processes -OR- Aluminum for Solder Paste / IR Reflow Processes

Carrier Pallets
Titanium pallets used in wave solder will not contaminate the solder bath. Aluminum pallets can be used in solder paste IR reflow applications. The pallet is designed for use as circuit board and flex circuit carrying pallets for wave solder machines and solder reflow ovens.

Pallet Features
» Metallic pallets have a superior ability to keep critical components cool during the wave solder or IR reflow process.
» Designed with strength to withstand operator abuse and repeated use without damage.
» Anti-flex reinforcement rods are carefully designed to allow frequent high temperature cycles through wave soldering without warping or breaking loose
» Dimensional stability so that fit and alignment are the same time after time.
» Engraved lettering provides easy to read part number labeling.

Tooling Pin Insertion Base Styles
Tooling pins are installed using an automated machine for positioning, and insertion. This technique provides perpendicularly exceeding 1/1000" per linear foot, and prevents drift due to side scoring and chipping. The end result is an extremely high degree of accuracy and repeatability in pin positioning. Above all, a tighter press fit for better mechanical reliability.
Other techniques for even higher reliability are as shown above:
» Swaged pins.
» Grove and glued pins (high temperature epoxy)..
» Cap captured pins.

Tooling Pin Body Styles
A variety of pin body styles are available. The styles are listed from the lower cost to the most expensive. The tradeoff is pin placement longevity. The stainless steel pins expand and contract at different rates than the pallet material, and can loosen up over time. The flanged step pin holds the best but costs the most. Common pin styles available are:
» Straight pins
» Step pins
» Flanged Step Pins.

Tooling Pin Tip Styles
» Round head for standard through holes
» Diamond head for slotted holes
» Elongated round head for precision aligning slotted holes
