I think you just answered a questioned that I never thought to ask. Are bulk parts manufactured differently than standard tape and reel parts? That would explain why there is a bigger price difference in parts from Murata and not from others. As I

Pick up correction (as far as position) is already available on newer model chipshooters. This doesn't address upside-down fed resistors. The link I provided for Murata tells a story of increased reliability and reduced cost. As components get sma

I don't think it's possible for a turret machine, but I seem to remember some sales guy talking about a camera on his machine that did look at the part before it picked it up. As far as bulk feeding goes, how would you ensure the resistors are right

So, to really get reliable pickup rates from new bulk feeders, I just need to replace all the chip shooters we have with more recent ones with pickup correction capability. So where is the saving? ;-) -Upside down resistors? not an issue. so what if

Claude, I know alot of equipment manufacturers that would like to talk to you about replacing all of your chipshooters! Of course, this will never happen. There probably won't be any sold until all of the used chipshooters are absorbed from the use

Q1: Are the markings on resistors the actual value? A1: Generally, resistor marking indicates the value of the device, where the first two digits are the value and the third digit is the multiplier. Q2: Do AOI machines look for these markings or do

"Use the pad mating to lead wetting area." If I get your drift, we're talking about the minimum lead area (assuming the pad has an area that's at least as large as the lead) required to be wetted by IPC-610. Hmmmm...that would take some calculation

Hi all, We are using small CSPs (10x10mm) in one of our products which has a big ground pad in the center (7x7mm). The maximum voiding allowed on this big pad is also no greater than 25% which we are finding very hard to achieve. The centre pad ha

We just had this issue a couple months ago with a single sided FR-4 board which was scored. We found that the design was a factor but also the depth of the v-score. Since then we have re-designed the part further away from the score line. At the same

Hello, As an Ex-Sanyo engineer I agree with the previous reply. Use EP1 sparingly. You may find that the nozzle sleeves are scored when you remove them. This is from lack of cleaning. You can only buy the sleeve and bearing from sanyo which is a was
