We trasfered a product in some time ago and they were using erasers to hold down parts. Some parts will move around during wave and some parts just need to be positioned correctly after wave so hold downs are required. I personaly have never used a b

I have used these bean bags for several years now. They work great for holding down odd formed components during the wave process. I use the cotton ESD smock material and cut out what ever size I need. Works Great!.

Hi, We have a customer who give us a 20K board contract each year. It's only thru-hole components.The baord is HASL plated. So we pass it into our wave. No problems. Recently, our customer decided to go into GOLD PLATED finish. We take the same re
