Brad, I went through the arduous process of selecting new P&P equipment last year. I looked at all of the same machines you are considering in addition to Juki and Europlacer. We are a high mix low volume shop as well and were running Quad "C" mac

Hi Tom, Thanks for the compliment. I've been researching and planning for the time that my company would go lead free since late in 1999. I hear you there, how do we know that the component is lead free. Baring a leap of faith with your vendors, I

There is: * NO information to indicate leadfree solder is at all reliable regardless of class of operation. * NO material model for leadfree solder, whereas the model for lead solder was developed over many years back during a time when companies be

Hi, We have been running the same stencils for about a year, 5 thou thick, 1-mm pitch BGA's and every-things been ok, but then suddenly over the last week, 2 different products have had paste release issues with the BGA. It's odd because nothings c

If your have enough hours on a machine that you have all the windmills off for maintenance, it would seem to be a good thing to check this height. It would take only a few minutes to put a dial indicator in and manually crank the machine to the botto

The manual gives you a fair idea here. Reference for the Yamaha manual is THE6006 - I don't know if Philips is the same. Cause is either overload or overcurrent. The manual suggests that you can tweak the trimmers on the driver board but these are us

The hasl joint looks fuller (and is easier to inspect)because it has more solder volume. Think about it. Your pre-plating your board with solder (before you add more solder). I doubt your getting 0.3 mils of hasl.....probably more like 1.3 to 3.0

Hi, It seems weird that an automated pick and place machine at a board shop would not be up to NASA standards, but placing the components by hand would be. However most SMT will self center a bit, so if your close enough, you should be ok. You rea

You mentioned you only do 1-4 boards per program per year, and that you're doing 8-14hrs per board. Does that mean you're only doing a couple of boards per week in total? In other words: consider the amount of running time you expect to get on the ma

Hi Daan, What we did in the time was pareto analyses on all board designs to determine the critical areas (mainly design errors) and only inspect those specific problem areas. Every batch had a copy of the PC board with problem areas marked and only
