I did convert YM 84V for 0402, base on my expperience , this approach is not really good.This model were not really meant for 0402 placement. Nozzle H ID is really small and prone to clogging, therefore cleaning every 2 hours is a necessity( not id

I have been working with GSMs since 1999. Mostly, I've been programming them but for the past 2 1/2 years or so I've also gotten to know them mechanically. I think they are great machines. If you are looking at Flex head GSMs (4-spindle) they won'

"I read a study a while back by IBM that showed too strong a vacuum would cause too much moisture to enter the bags." That's what the nitrogen is for. If you pull a vacuum w/o backfilling with something dry, like nitrogen, pretty soon the vacuum ove

A recent thread regarding the ACE KISS equipment has me wondering if anyone is happy with their choice in selective equipment. I don't see much mentioned about Pillarhouse, Juki, ERSA and some of the others. We're currently debating whether to inve

"...but does the Quad have any sensing of what is going on in the feeder?" Not with the feeders we use. Same deal as the Topaz, i.e., the machine knows if the nozzle has a part on it, but doesn't know what is happening in the feeder. There are "smar

Since no one has responded I'll give you what little I know. My last place of employment used MSH-IIs and an MPAV-2B. As far as I know there is no optimisation capability at the machine like there is with your Topaz. The programmer used Panasonic

We have an outdated Metcal rework station and are thinking about purchasing a new one. We need something that has heat profile capability. We don't really need anything automated, just something that's affordable, durable, and gets the job done. Does
