Electrical Contact Stamping and Cleanliness

We have a long history of stamping, cleaning and handling electrical parts it has been a mainstay of our manufacturing.
Cleanliness of the stamped parts is critical for many downstream processes for example soldering “wettability” contaminants and lube or cleaner residue can impair the downstream processes.
Using the correct cleansing agent and process for the material and plating of the stamped part is critical as some agents can cause delayed corrosion.
Many electrical components are stamped using a water emulsion lubrication that evaporates also called “vanishing lube”.

Metal particles are especially critical as they could cause an electrical system to short circuit. To reduce the possibility of metal particles the cutting section of the die shall be designed to avoid thin material cuts and or overlaps that could potentially produce shaved metal pieces that may or may not be attached to the part. These particles are often labeled “Give Off Particles” or “Swarf”

Avoiding other Particles like lint, fiber or cardboard are usually caused by the wrong packaging.
