It's nice to be able to do things in house, and it's good to have somewhere without commercial pressures to learn and make mistakes, so I can understand where you are trying to go. Those machines look a little lightweight for consistent quality pr

| Read an earlier thread about using glass slugs to determine placement CPk. Can it actually be done this way? What's the procedure? Be interesting to know 'cause if it's feasible, I'd probably get myself a kit. None of us here are stat's experts

The issue of using ultrasonic technology for post reflow de-fluxing presents challenges in two categories: Controversial: Although there are recent studies that indicate acceptance with ultrasonic technology on populated assemblies, there remains si

Spanky, It sounds like you are looking for a recipe to use when you do get an assembly in that has 0201's on it. We have worked with our customers worldwide in the development of the process to use 0201's. Most equipment manufacturers out there

| I am interested in seeing how some of you quote smt work. Currently we quote off a bom without component packages known then look in data books to find out what type of component they are. This job will be mine soon but i really believe there is a

Since you are mostly concerned about the flux and suspect an application issue, you need to do a few things to validate whats going on. 1. Forget about speed of processing, length of time to do the job. Focus on accuracy first, then speed. with that

Comments are: * Some people use calibrated boards and components to remove sources of variation when using their CMM to measure placement accuracy. Sources of supply are listed in the fine SMTnet Archives. * It�s unclear that a single board will mee

Messy. Messy. Messy. Consider gluing these components, until you control your process. It is unclear to us that a single factor drives these defects, but multiple factors that need to be tuned to work well together. PAD DIMENSIONS * Some SM-782 pa

We are a company that designs a product but gets the PCB fabricated and the surface mount assembly done out of house. The product then comes in house and we test it, do some final assembly on it, and ship it. We recently had a prototype run of PCB'
