Hi All, I wasn't sure how this would turn out until I ran some production. As I suspected, after every nozzle change the machine dumps the first 3 pickups, checks the nozzle height again (function 30?) and then begins placing with correction with n

All - I'm hoping I can get a little feedback here on my package libraries for my Mydata machines. I have four tied to a server right now, and I have several operators that apparently like to make packages, so I have some called 0805-05-A-MY-9-2 and t

John, As Dave says, never clean raw paste. Let it sit for at least 24 hrs if you can and use a plastic spatula to wipe off the bulk of it. The "drier" the paste the easier it is to remove without it travelling down vias etc. You will then have to cho

Okay, here's the deal-e-o....I need to find the Nation's Best BGA Rework Specialists. I have 50 PCBs each measuring about one square inch, that need to have a BGA Ring Socket Removed, eight capacitors removed, and a new ring socket installed. Sounds

We currently are building a pcb that has gold fingers, about 36 in a concave V overall shape from .275 on the outside edge fingers tapering down to .197 in the middle of the 2 inch span that plugs into a shelf connector. These fingers are on both sid

Why not? If You think it has a bussiness case so go for it. We are currently using a firm that has 24h delivery time if neccesary (we need to order before 9'clock in the morning)and we once in a while use this for some prototypes. Their regular shipm

Pallet angle is usually pretty good. Lead length is also another good thing to keep as short as possible. Air Knives don't work that well. Also check your board. Make sure you have solder resist between each and every thru-hole pad. If the board

We're in the process of trying to select a rebuilt, refurbished, or well serviced flexible placer, something that's capable of placing in the neighborhood of 10k and up. We're a high mix low volume shop so easy setups is key. I'd be looking at a MY-9
