I always put the step on the squeegee side. You'll get some "shadowing" effect on any parts in close proximity to the stepped up region. It should be manageable with proper board / stencil design.

I've never seen this Can you post picture? aluminum may sink heat and shadow component if too big

Hello, My company manufactures MLB's and is currently experiences so many voids due to a mistake in direct metallization (shadow line). We have tried testing every chemical component in the line and every possible maintenance. The scrap rate is goi

Titanium wall could go down to 10mil thickness. Just make sure this location runs on the back end of the pallet flow to avoid shadowing and allow solder to wet in this area.

Larry, SOTs are a wonderful thing to try and wave solder! They are about as nice as Tant caps. I have found that shadowing is usually the biggest problem assuming that the other wave parameters are good, in your case it seems that they are. Couple

Hey C.K, If you are looking for inspection of the solder paste before reflow, there are many types of inspection: 1.Paste height measurements at random positions 2.3D inspection with shadow contrast capabilities based on an autocad format 3.3D inspec

Many people use the same spacing [and pad designs] as they use for primary side SMT. We don�t. DOWN STREAM SMT-TO-SMT SPACING: In addition to proper orientation, components cannot be immediately upstream of terminations that are to be soldered or b

In short this guys are not well updated on the new technology of SPI. True, 3D IN LINE SPI is no longer a slow machine. Try checking some brand like Cyberoptics,Synapse imaging,SEIMENS,KOHYOUNG and many others...they can match the speed os some mount

You would be suprised what you can see with even a simple Xray machine. The engineers upstairs wanted to see if the xray could confirm there was an open via on a thin dense board with several layers. I thought (but didn't say) no way. But with carefu
