I have lots of experience with thermosonic gold ball bonding. You can read the literature and you will probably find some papers that say you can do it. I have never been able to do it. We gold ball bond all day long with little problems at all bu

I'm hoping that someone may be able to shed some light on this error we've been getting on our DEK 265LT printer. Several months ago we began getting a "Rising table position error" after the operator would open the hood to load paste or after changi

everyone made good observations in the arena of improvements. being rather pessimistic today, I'd like to say the one core area of little (if none at all) improvement is the over-reliance of human (aid/non-aid) inspection of SMT output soldering de

Normally, we try to limit the over print of the paste to the width of the pad on both sides. If you are using 500um pad, then I wouldn't try over a 1500um aperture. Mario Scalzo, CSMTPE, Dartmouth 6 Sigma Green Belt Technical Support Engineer - Ind

Russ: You've got stop soft-peddling this stuff. This doesn't sound like "poor solderability." It sounds like "no solderability." It also sounds like you�re dead meat. Three places to call: 1 Board supplier to get their suggestions on unsolderab

if a solder has over 85% lead its classed as RoHS complient because its difficult to achive the same melting point with anything else (298degrees). a few other alloys with a similar range are ; % % 266E266 82.6 Cd 17.4 Zn 271MP 100 Bi 280E2

Yes, there is a limitation with Transmission X-ray on double-side SMT boards, ie.: back-to-back solder joints, components on bttom side over a solder joint.

There are always work-arounds to these types of problems. But in this case this limitation is most likley a safety feature. I would not recommend defeating a safety feature that could result in your factory burning to the ground.

We have both NXT and AIM. Be aware of the width limitation (250mm?)on the M3 module, if you go over it then you have to pair with an adjacent module to build the board.

Hi, We have a very annoying problem with a Philips Orion 2 SMT machine. It displays the error message "Second Limit Over" a few times per shift and it's impossible to make the machine work again unless it is turned off from the mains. It stops in th
