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

I have been soldering 0603 components on the bottom side using a glue and wave solder process for a long time. Bridging has not been a common problem. However, it is inherent on the design engineers to follow good manufacturability planning when la

| Hi Folks, | This is my first surface mount board, so I asked our assembly house for some tips. They said only passives on the bottom side-preferably no smaller than 0805, 0603 only if I have to. I would think that an SOT-23 would be OK on the botto

When going to a "no clean" process, there are always two items that will require cleaning - stencils and pallets. You may also have a requirement to clean misprinted PCBs and possibly SMD adhesives. The Smart Sonic Stencil/Pallet Cleaning Process

We haven't built these yet. The customer was in layout at the time and I was looking for any flags from others to determine if I should have them change the layout as I've not seen this before. From your response and others that I've received, it s
