Choices are: * IPC-RB-276 [superseded by IPC-6011/6012], Section 5 discusses some basic shipping and packaging requirements. Also, it references ASTM D-3951 and MIL-P-116. * Universal Instruments has done a nice job putting together a packaging speci

I'm sorry, Dave - I didn't make myself very clear. Yes, this space (not really a "gap") is filled with solid solder. For instance, if you place a gull-wing component in solder paste, after reflow, there will probably be a thin film of solidied solder

I would suggest checking the feeder, MVF and MSR are both turret type and dont have the capability auto pik adjust in y. Y offset pick up would lead to : 1. Over turn component. 2. Missing component. Turret sequence is pick, recognize an

Hi all, Sorry for the late reply..I am sure it is flux residue..Found no such symptom as Grey mention above. This is non clean process and no way we can clean this whole big board(Server) with any kind of flux removal...Currently, the ICT probe pre

I would be glad to help you eliminate the solder balling and beading that you are seeing. As this is a fairly common defect, I would like to forward you an Application Note that we have developed that explains the cause and possible solutions. Most

OK... My problem with BTUs is that they are getting stopped up because the flux is not going from vapor form to liquid form; instead it is crystalizing (looks like a blizzard took place in the flux box and chiller boxes) and clogging up the flux box,

I like this definition the best. After years of sales of pick and place and other, this is always still a topic of discussion. If your customer's cycle time involves building a board in two different machines, then I would suggest measuring and add

I am in the process of characterising a new vapour phase reflow system and am interested to learn if anyone out there has ever come across time/temperature datalogging equipment capable of being run through the entire process (including vacuum) along

It makes sense if you think about it. Siemens was a dead company ready to fold up their tents back in the 80's and early 90's. To their credit they stuck to their platform...got somewhat lucky and the market sort of came to them as the wave of users

Siemens is the General Electric of Europe. Like GE, Siemens typically is in the top 3 positions ($ market share and profit) or they exit the business. In total revenue I expect Siemens to be in the top 2-3 globally. In units I expect Yamaha has the
