Hi Experts, Would you point me into the right direction? I am looking a way to download data from smt machinery to avoid having to the in-situ machine's panel, and as we have mixed brands in multiple lines, it gets very hard to analize data. Is the

Hi Alexei, Is your solution opensource? Yes, I understand that most manufacturers try to sell licenses for their own SPC softwares, however sometime the information is stored in a file that could be opened.... for example hitachi HT-100 has Recall D

Process capability indices are pretty well documented. Consider: 1 A good general SPC book like: Statistical Quality Control; EL Grant & RS Leavenworth; Mcgraw-Hill; ISBN 0078443547 2 Other good books are: Statistical Process Control For SMT; WS

does anyone know what environment factors(specifications?) and process control parameters(printer & reflow?) are optimal for running SMT using type 4 and type 5 solder paste respectively? Any pitfalls to avoid? The product we have been asked to use

Hello all! For my mechanical engineering study I want to etch a strain gauge in the Wheatstone bridge configuration in a copper layer of an PCB. The goal is to measure the strain occurring in an PCB even during the press process! We can measure with

Juran�s "Quality Control Handbook" [McGraw Hill] is an excellent resource. It is, by and large, accessible by those who are not conversant in the Central Limit Theorem [like who is?], although it will help explain whatever that thing is that I just

| I am just implementing a Statistical Process Control to the SMD. | A few simple questions: | 1. Is it necessary to perform a sampling plan for suppliers inspection? | 2. What are the basical points to control ourself and inspection at a supplier? I

My company is looking to perform "real time" statistical process control on our current SMT operations. I have identified the critical processes for SPC but have not had much luck in finding a system(s) that can monitor the required processes for my

The tendancy always has been "when in doubt, touch it up"... this is not the way to "verify the process" and is not the best strategy for multiple reasons (unessecary rework, additional labor costs, as well as making the solder joint more brittle, [i
