I have been asked to get a 4712B onserter running again and have a few questions; Does this make sense in terms of reliability and maintainability? Is the 4712B desigened as a standalone only machine? Also, I need documentation and software if anyone

No, it makes no sense at all. This is a very old and long obsoleted machine and a very poor design to boot. I know first hand because I worked on them many moons ago. The Onserter was designed as a "pass-thru" machine. Software and manuals will be h

WOW, a 300ml syringe!!!! Now, that is one BIG-assed syringe. [I assume you mean �30ml�] Thoughts are: * Buy through distribution, for instance http://www.loctite.com/distributor/ * Buy your cases in smaller syringes. 10 & 30ml syringes are standar

Tried both, with no success. The big guys are pretty secretive about how they do things. The lawyer understands arbitration and things like that, but doesn't have a clue about customer furnished materials or volume pricing. I have found that IPC is w

Hi Guys, Quick question I want to mothball a full SMT line ie shut it down so it dose not lose any deprication...I need a way of tamper proofing the equipment so that our technians do not canibal spares from the machines. Any ideas...of how to do thi

First of all, your machines are going to depreciate regardless of how or where you store them. Secondly, if your techs are canibals, I suggest wraping the machines with razor sharp barbed wire. Finally, if they NEED a part from your 'mothballed' mach

Contact the fabricator of this part for their recommendations. There is about as many different approaches to soldering thermistors as there is thermistors. You imply that this is a SMT style package. If that is correct, it's curious that the comp

One of our board fabricators says that carbon inks should be selected based on the process to be used by the assembler. So, their take on this question has some inks that work fine with nc fluxes, others that do not. They suggest: * Determining t

What is the maximum allowable thermal ramp rate for wave solder. We have a "short" machine used for selective soldering. To get the boards up to temp, we need to exceed our normal 2�C/sec. Are there any IPC documents governing this process? Anyon
