Greg, As Dave pointed out, the main reason to bake components is to remove absorbed moisture from moisture-sensitive components. All you need to know on this subject, including the specific bake conditions (temperature and duration) are clearly s

No need to make rocket science out it. Buy an AOI mchine. If that's too expensive, scrap a board to use as a sample. Can't do that, use a digital camera and snap a couple pix of a good board and make some kick ass work instructions to use. Can't

Save your money. I tried to buy one for a G3 before, had one actually shipped in, and had to return it because it didn't fit the machine. Some other options: 1) buy a tape and reel machine cost you about $10K, but then you have control over

Hello Peterson, If the contact tails protruded enough on the underside of the PCB, then you could do a "reverse" press fit. I do not believe that to be the case with the VHDM. Placement equipment is out of my bailiwick but; Usually small SMT connec

Sometimes when a customer has sent parts on reel without any leader, we will take out the first 5-8 parts and then tie off the cover tape with some leftover tape from the last run. We keep those parts we removed and then place them back in the feede

If you are using a well maintained chip shooter, you should not see more than 1%-2%, and that is on the high side. Most pick and place machines (depending on what they utilize) with laser, vision, mechanical centering will most likely reject a diffe

We are currently NOT using bulk, even though we looked into as a means of reducing machine time and component cost. Unfortunately, since bulk cassettes did NOT take the industry by storm as it was predicted years ago, we were stuck with long lead ti

If it takes an extra step, then it is costing my company money to pay that person to do that task. Besides, I prefer to keep the stock personnel busy counting reels from shipments and preparing kits for the production floor. Kind of sounds like buy

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

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
