Good story. Bad idea. You need standards. You need training in those standards. Call IPC to get both. You're wasting time and money with this cockamamey scheme to outsource your inspection standard making. And who says the bozo or bozette tha

Janet, If you do not have any SMT experianced personel hire a consultant. You can find them everywhere on this site even if they say they don't participate or even agree with SMTNET. Whoever you choose can give you the direction and understanding ne

Armin: The stuff that Jax says is spot-on from a "bean counter" stand-point. Not that I'm say that Jax is one, he's aparently had training in dealing with them. But there's another apect that doesn't show on the spreadsheets and factor anaylsis. I

I have to agree with you Wolfgang. Admittedly it's my first look at it but I don't think my opinion will change much. At this point I wish I had taken the time to respond to Brian's request to beta test the "new" site. Maybe I could have made a di

Most robust wave soldering machines will cope with lead free alloys. The temperatures in air that we have run has been between 260-265C. In my opinion the dross generation has not been significantly effected. I was doing a workshop for a well known

Most of the problems that you will find with NC is visual. I have not found or heard of any real evidence that NC causes component or board failures. The residue has extremely high resistance, which actually gets higher as time goes on. It's a paradi

Does anyone consider the use of a Cyberoptics LSM solder paste thickness measurement system to be a valid test in determining the viscosity of solder paste. This procedure was proposed as an alternative to using the Malcolm gage for viscosity testing

Tony Although I agree in principle with Dean that 45 Degrees would be ideal, most of the squeegees I have worked with have been 60 Degrees to the stencil surface. This seems to work best with metal squeegees when printing HASL boards, because the sl

Your point about thermosets getting soft in the preheater of the wave is well taken. But an adhesive that is used past its expiry or other up-front lack of process control represent 99 & 44/100 percent of the reason for �glued parts falling off in
