I have a board which contains brass spacers. The spacers will pass through the wave during soldering. I found a silicon-rubber cap that can prevent solder climbing up into the spacer. However, the cap influence the wave flow and reduce the solderabil

Spacerwoman: Carol is a professional spacer problem fighter (we think). When people have problems with spacers, they call on SPACERWOMAN!!!!! Here she is to save the day � ;-) Selecting a spacer made of brass is a good choice for many applicatio

It seems that supply issues are really plaguing BIVAR for their spacers. Is there an alternative company that makes equivalent spacers? It's the 901, 903, 938 series spacers that I can't find much of an alternative market.

Hi, We have a couple of pcb's with PTH Crystal. We are looking for a spacer to be placed between the metallic body of the crystal and the via pad/land as they tend to short if wave soldered without a spacer. The spacer we are looking for is somethin

Hi, I tried to use high temperature solder (540 - 570F)to connect four spacers on the board. The solder mask around the spacers wrinkled a lot.I can even see a few bulbs around it. I use hot plate and solder rings. After hot plate is heated to appr

Hi, thank you for the idea. I may try solder iron, but it much more slower since I have to solder spacers one by one. a stimpson press is used to press the spacer on the board and the edges of the spacers are rolled. Then we solder the edges to

We can't tell you much without additional information about your situation. For example: * How is the spacer attached to your board? * You specifically mentioned Printec. What are the things about Printec's process that are out of the ordinary for

Armin: Are you washing the brds after wave? If so there are water soluble spacers out there that work great and are removed through the washing process!

Bivar's area code has changed to 949. They also have a website...www.bivar.com. I am using one of their water soluble spacers for a crystal, and it works great. They also have permanent ones. Brian
