These ones from ALTERA the QFFP-304 0.5mm weight: 32gr. used to give us a really headache in the past. Not only soldering issue:s but also the placement in x-y-theta! The stencil thickness of ours is 0.13mm and because of ohter compomponent packages,

Hi Guys, So I work for a small contract manufacturer which caters mainly to the defense sector. As such, our customers haven't (yet) had a great need to incorporate 01005's into their designs. Looking forward, we decided to "take the plunge" and dia

You should ask yourself a bunch of questions before you consider going down this path. The first being where are the bottlenecks in your existing line and is there anything you can do to eliminate or decrease there bottleneckness (made up word). I

I'd recommend not using them, personally :) The long term reliability of the SMT joint is suspect, IMHO. I had them for an in-house manufactured bed-of-nails test fixture for testing somewhere north of 5000 units....after the first 100, we were rep

John, I'll try to take a crack at it. We manufacture our own boards, and have a high mix. We currently have BOTH a Camalot 2800 Dispenser and a DEK 260 Screen printer. We use the camalot for glue applications, and prototype paste. We use the printe

Dear Masdi, Solder beading (as opposed to solder balls) is usually caused by volume of solder paste, displacement of solder paste when component is placed and sometimes the proximity of the solder depositions for that component. Basically, a small a

Currently where I work, we are busy running trials with smaller component sizes. Consumer Electronics is being driven to smaller and smaller products. Just look at the short history of the cell phone. Remeber when they used to look like Army Walki

I don't know the specs. of our MSHII's, as I'm sort of detached from that part of the process, but supposedly they are capable. Panasonic also recommends we buy all new feeders (well, big surprise there), because of the risks involved with retrofitti
