This is indeed yet another proof that under impulse of the RoHS directives all norms are flushed down the drain. Bean counters are slowly but surely taking over our industry because they no longer face resistance by form of standards. Even the basic

In all fairness no one has the answer for you, non of the lead-free alloys has been long enough in use or have supporting long-term reliability data. No matter what alloy you will use, your company will be at risk, that�s why so many exemptions are a

Dear All, Thank you very much for your advices and comments. I appreciate that. Does anyone have any idea how much the good working condition second hand MY9 will cost? And how does MY9 compare to SMT 2350C in term of cost and performance? Regardin

We currently use both machines side by side in our lab now and LPKF is by far the better machine. Both are comparable systems to each other but the T-Tech machine always seems to have problems of some sort and their tech support department isn�t ve

Hey All, Thanks for all of your help to date. While running the nozzle height test I noticed that the Z-rod is bent. Probably happened after setting the "X closed loop soft home" back to 50 from 384 which was probably why the nozzle slammed into t

Hi Pavel, Real Chunks, Thanks for your valuable inputs..Selecting the correct location for board profiling is critical in determining the solder joint quality. Am I right to say TC wire attachment locations priority should be as below: (1) Thermal

We use a fairly simple system. IPC put out standards 7912A and 9261A to define opportunities. Basicly the "number of components" + "number of solder joints" = "number of opportunities." Some six sigma benchmarking studies indicated "Sigma Level" =

Yes, I am currently using Viromet 347 at the moment for my SMT lines. 100-150, 35 sec 150-207, 40 sec 207-above, 80 sec peak temp: 225 deg C. It is compatible to SAC paste in term of solderability and wettability. But in term of mechanical property (

Let me just shortly explain why do I open this thread. In my corporation in different plants we use same components at the same machines in different products(Fuji machines). I would like to create kind of global database of shapes ( its in FujiFlexa

Hi Loco, Good point!! The good old glass plate works just fine as long as the conveyor or carriers have L shaped fingers. A glass plate is usually about a � inch thick (a lot thicker than the actual board). With L shaped fingers the bottom of the gl
