Hi Harrit, We are processing SMT eleco's normally - up to around 8mm in height, the larger sizes can still be avoided and are through hole as the cost of them outweigh the benefit of surface mounting them (although we did get good results on test fo

It depends on a number of factors - including as Russ pointed out, complexity (sometimes you need to create very complex profiles if you have large BGAs and other such components, which require at least 7 heated zones), then you have size, required l

Um...for you mylar guys....esd safe? Why worry about the first two prints. Worry if they power up or not when sent to funcitonal test. Zapp! I think I know where this is comming from. It is not that uncommon to have a sacrificial print. However,

Greg, I recently faced this problem at a customer though the machine was Topaz X but the problem was same. So I suggest you first check if the GOOD LED is ON on the Servo card down in the MCX box. Also check the same GOOD LED on the System board in

In my prior posting, I didn't exactly understood what You have in mind. I now understand that You want to get something for free, that everybody else need to pay for. If this is only for personal use so that You will be more skilled at Your work? Th

We have utilized one of these for about 6mos. now (is that right Larry? I know you're reading this.) So far it has proven to be a very good machine. Getting the vision right on chip caps can be tricky and sometimes frustrating but once they are rig

Hi, I'd be inclined to go with the through hole capacitor, as to surface mount it you would probably need to go for an elco (ceramics & films don't do that value in that voltage, & you'd be hard pressed to get a tant in that voltage). SMD Elcos a

Hi Grant, Murata do 0402 chip caps on 50K reels - example: GRM1555C1H101JZ01J 0402, 100pf, NPO/C0G 50V 5% (make sure the final letter is included - the J denotes the reel size - D is standard 10K) Rohm MCR01 series (0402 resistors) come on 6inch, 1

I can't see how prompt washing of the boards could cause a problem in X7R but not in Y5V or NPO. Yes, if you dropped a board into the wash straight out of the oven without letting it cool down then it's not going to like it, but surely no-one does t

Hello Chris, To be honest, it's hard to believe you could not bond to ENIG at all. Yes, the gold layer is thin and hard, but it just narrows the process window and does not make the bonding impossible. I say this, because we have been using TS gold w
