Just one minor point to bear in mind, most stencils have tapered apertures. If you want to get really accurate volumes you will need to work put the volume based on the taper of the walls. Probably going to far but at least you can sound knowledgeab

We are using the tapered nozzles.

Yo Ho! I'm a little late to the party, sorry! Flex can be a simple PCB to process through Screen, Pick & Place & Reflow, if the card is designed properly. 4 symmetrical tooling holes .125" diameter and 5mm in on each corner of the card. Wedge Effect:

Electropolishing definitely improves the print characteristics of both Laser-cut and Chem-etch stencils. The caveat here is avoid over polishing which results in rounding of the edges and/or enlargement of the openings. Over polishing is typically th

I think we aim for the DOT on the flat. If you get too close to the lens, the taper on the nozzle hits the lens, and you don't get enough vacuum. There is not much room for error on pickup.

Yes, yes, I agree with American man, URL, on all his points about having to know the overall process 1st. I'm surprised he doesn't have his own free consulting website. Other things you can try are: * "Dog-bone" apertures... taper down the apertur

I have found that it all depends on your leadtime. I've found that tube and tray are easier to get then taper nad reel. I figure it has to do more with the vender. It's much easier to sell small quantites (ie tubes) then to try and sell a huge reel o

We have solved our MCSB problems by using standard homeplate designs on all of our resistors and caps. I use a 50% taper and have achieved great results with 0402-1206 parts using both tin/lead and SAC305 paste. We use Amtech paste.

Hello Sr.Tech, There have been two types of nozzles made by Fuji for 0201's one was a 1mm tapered to .4mm and the other has a straight .4mm tube. Has one superceded the other and if you have used both types, did one work better than the other? Asking
