I have recently signed onto a company with very little board assembly experience. I am trying to develop a process control and continuous process improvement program for a new surface mount line, but have run into several people who are not really i

No N2. We could not fix a benefit for N2 in our minds. Just fold the excess bag material over to expell most air and then seal the bag. [Have you assessed the benefit of N2?] F Monette can tell you stories about little versus more pressure. If he

Imm silver holds-up to multiple thermal cycles very well. The things, we guess, are happening to make imm silver tough to solder after heating and sitting are: * Oxidation of the silver. * Reduction of the co-deposited organic anti-tarnish [used in

Wow, this has been real interesting reading. Kind of like a Jerry Springer Forum. "Today on SMTA Forum, cranky engineers and over zealous sales people square off to decide if the replies to the thread are appropriate" When some one asks a questions

My suggestion is to conduct a Design For Manufacturing (DFM)study on the assembly in question. Pay particular attention to the pad sizes, component lead dimensions and satisfy yourself that those two factors are correct. Given that pads match compone

First, I don't have a clear fix on the problem. Please drill-down to more detail. We appreciate that you probably don't know the parlance. Just describe what you have and then what you'd like to have. Second, most 0402 LED are fabricated just lik

Board fabricators purchase laminate in preferred panel sizes, such as: 16 x 18 inches, 18 x 24 inches, and 21 x 24 inches. A larger panel size provides more effective cost per unit area processed. In producing a board, the fabricator requires maybe 3

the reason you don't want to use PPM is exactly the reason you need to. You cannot compare a square 1" block to a multi faceted custom machine part. In SMT assembly you will usually find that all 0603 and larger discreetes,25mil pitch, etc. are pro
