| We have a double sided pcb that is surface mount on both sides. Now a Through Hole connector has been added. Appart from hand soldering does anyone have info. on reflow soldering the part. The connector is 0.1mm pitch, square legs. | 1) Do you need

| We are in need of a low cost system for the rework of | various SMT devices. Ideally the machine should support BGA, | SQFP, and large PLCCs. | Is it a dream to ask for SMT tweezers, a regular iron, | and a convection pencil as well? Want a machin

Good luck in your conquest. I have been struggling with the same issues for some time now. I have made the following conclusions. First, it is nearly impossible to establish parameters in SMT to perform X-Bar and R charts. Electronics is not as cl

Thanks to Scott for your reply, much appreciated. Are you aware of any new developments in this area? Particularly in respect to the solvents? We are aware that fluorine chemistry is now in-use with amazingly high boiling points. We understand that

First, not that it�s bad, but SM-782, the land pattern standard is a pretty far distance from a DFM check list. Now, if you�d said D-275 er more properly 222X, ama be twitchin� less. Second, your process should include two distinct elements: 1 Data

Dave , you know it's your cheery disposoition I love.... Ok so the process: Process is Double sided reflow for SMT & PTH via the wave. Like I said or did I, I forget and can't check back...it's a spray fluxer with noclean mutlicore NR3s-06 water b

Hey John, You're not alone, a lot of people have the same problem with different machines and material. What is your specific problem, just keeping SPC control? Or are your defects at the wave from the glue too? If it's a process problem, I found

To be honest with you, it doesn't really matter how you present the data, as long as you understand what the problems are. Bottom line is who cares what the numbers are unless you are doing something about it. Are you able to track the individual de

To clarify on "Opportunities"- With 1000 components, the opportunities are far greater than 1000. You have 1 opportunity per component for a component defect i.e. bent lead, damaged part, tested bad, etc. You have a second opportunity per component
