But that's how Purchasing is supposed to work, right? Then boast how they saved 50 bucks that day on buying slightly plemmed boards. Then you spend thousands of dollars over the course of the year reworking thru the plems. All the while management

Not to mention the couple hunnert they save by NOT getting an air ride truck to ship a new inline printer. You'd be amazed at what an E5 can do to a pallet in 3000 miles. I can't believe the thing worked.

It's been years since I worked with a Fuji. I only once resorted to the undocumented part class 255 (or whatever they call it) and that was when I was working midnight shift. The smaller nozzle working better than the larger nozzle makes me wonder a

Hi Tony, as you might guess, a Nozzle Mfg. has stepped into this conversation. Having worked with many small, mid-size, and Fortune 500 companies for almost 15 years we have seen many "parts" pick up challenges. We were the first to offer "Complia

Question: I am going to start placing 3mm x 3mm plastic smt leds and want the absolute lowest errors caused by the nozzle either dropping or allowing the part to shift. Would a 2.5mm nozzle be too big for the 3mm part. My logic is that the more surfa

Hey Thanks! Yep, they are pricey but I think it would be a worth while expense to safegaurd $250,000 worth of leds! I will tell the powers that be and see if I can squeeze out some cash. If I scrap one loaded board could I use it for profiling 20 to

Crappy piles? Weren't they a hard rock band in the 80's? I know on most of our boards the little silk screen dot is just the component identifier in really small font when looked at in Gerber. But this dot isn't very big, so I see how it can affec

Chalk this one up to semantics. Regardless of when you start pumping (do you use a needle with a foot? In that case the pump will run when the foot touches the board), your volume of epoxy is the same. You just have less room for it where there is si

Most QFP 128s have a 0.16mm wide lead. Might have to modify your pads if you'r buying some odd ball part. But generally 0.2mm should be OK for this part. You may never get good toe wetting. Most QFPs are cut apart after plating, thus the toes are

I have carried out some further measurements on the device and the results are as follow: Component Lead width measures 183 microns. Actuals PAD width measures 158 microns. What I am thinking is that the lead is attracting the solder hence prevent
