Normally if the package is defined properly I would expect your machine to place it correctly but we have some parts pushed right down to the pads. If the paste is centered, and the parts are centered, and you have obvious bridging potential coming

I have several reels of components I purchased from Chinese source. During pick and place, the tapes keep breaking (they tear diagonally along the reel). I notice the tape is very tight if I try to pull through manually. I tried several over 12mm fe

Would anyone have a link to a site or a book suggestion for creating assembly documentation. I am not looking for ISO 9X or anything just some ways I can document the process for assembly of products at the board level. Most of my experience was in R

Look at what you make, what kind of questions come back to the office from the factory floor when documentation is poor or non-existent. Template your documentation accordingly, there should be enough in there that staff don't need to ask questions,

Hello SMTA, I have been approached about researching the potential for electroplating 3D printed plastic parts. Electroplating plastic has been around for a while, but with the rise of 3D printing, this option is becoming something worth investigati

I'd have thought that the surface finish would be pretty much the same as when printed as electroplating is monumentally thin. I've not tried plastics, but when plating metals the surface has to be pretty much perfect in order to get an attractive re

A few lifetimes ago I worked for a company that electroless plated plastic cases for computers. I can't remember if it was us or just us and one other company. The FCC said that computers had to be shielded. So plastic computer cases had to be plated

We mostly do it by package and/or functional description. Certainly you should be able to ignore any passives (chip caps, resistors, diodes), and plastic bodied ICs and SOTs which will cut down the research dramatically. Beyond that, we mostly jus

We do this often. Including fences with many internal structures. I assume you are hand soldering the fences. Are you heating the assembly during the soldering process? We typically have no issues with this operation, on a variety of assembly typ

While I agree that you need to see an MD ASAP, it might help your provider to actually know what you were breathing, and I would worry way less about the materials in the components than I would about the flux from the solder paste. Edited to add, a
