Hi Adam...thanks for your follow up comments. The auto inserter in the video is a machine from a time gone by...But quite impressive. Those machines are good for higher volume where high flexibility may not be required. not sure if all of the comp

"Do you think these machines are less appropriate for smaller lot sizes and PCB's with just a few through hole parts?" That depends. It will still save time if your lot sizes are small, as opposed to hand placement. I would not recommend buying an

Hi Reese, The UIC machine is (was) good for higher volumes. Do you think these machines are less appropriate for smaller lot sizes and PCB's with just a few through hole parts? Also, are the UIC through hole machines still fully supported with ampl

Thank You Adam...this is the type of input I am looking for. To summarize, you are an OEM that has gone through the process to remove most through hole parts from your assemblies. Those that remain are primarily connectors which may not require lea

So we all know through hole assembly hasn't been completely eradicated. I am doing some research as to the types of through hole assembly that still remain. My questions are related to through hole requirements and past, current and future methodol

Interesting, see we used to do a large amount of PTH but we have been able to convert most of those parts to SMT now. the majority of our PTH is connectors. I am doing some research as to the types of through hole assembly that still remain.- This d

Hi Dean, Thanks for the feedback. I suppose I should reveal the nature of my query. Contact Systems was founded by my father back in 1970. I worked there from 1983 until we closed the doors back in 2009. I acquired the assets and intellectual pro

You need to post a picture or describe your geometry better. Is this a through hole via in pad or is the via offset from the pad with no soldermask in between?

Al: We agree with AVFOM. You have a different problem than solder paste mesh selection. Most often, tombstoning occurs when the wetting forces on the two pads are unequal. Examples of things that can cause this are: * Pads are different * Board pad

The smallest finished hole available for 2 layer board is .020”. The smallest finished hole available for 4+ layer board is .014”. All holes are round and drilled through from top to bottom layer of board. No blind or buried vias. For holes = .15
