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

Hi, "glass wicking failure" we don't know what this is, but we suspect that the reflow process could very well be the root cause for some of our pcba with micro vias failure. Micro vias pcb we know to well (we don't like them at all). There are No p

Contractor mantra: * Profile is good * Boards are bad On profiles, the key question is: where did you take the profile? We�d guess cracked connections are giving the intermittent test results when pressing on the components. You use acoustic micro

We use a fairly simple system. IPC put out standards 7912A and 9261A to define opportunities. Basicly the "number of components" + "number of solder joints" = "number of opportunities." Some six sigma benchmarking studies indicated "Sigma Level" =

You are probably using a GSM since you mentioned "enhanced board setup". 1.- Your CAD data. It works better when all your data uses bottom left of the PCB as a board origin ( BO ). If my CAD does not use bottom left as a BO, then I edit the data in

The continuing saga - we got the IP-1 communicating with the MCS16 again by replacing a couple of chips on the VME1152 CPU board and now it's working again but have a new problem. The machine stops about every other time when changing nozzles with a

We have used thousands of them with no problems. They will not aid in "connector retention" unless you have a shear force at exactly the right angle. This is an advertising joke. They will help with alignment of the connector. Open your holes up so t

Proper care and calibration of feeders helps the most. Once repeatability of position is gone the machine's feeder offset will start to resemble the agility of a drunken sailor. That can manifest itself in vision errors or worse as placement problems

Hi everyone. While this isn't exactly SMT, I'm sure most of you at least utilize the technology; I'm looking for someone I can contact with questions regarding my BMEP-5T press. I've been charged with getting the process up and running, but it's been

Hello, Is anyone using an SMT pick&place machine to insert single contacts into PC boards? I have some boards that have 32 female contacts for 1mm pins, and 16 contacts for 0.5mm pins. I have been using Mill-Max for these contacts, getting the sma
