I was wondering if anyone has had any experience with either the Esec Micron 2 or the RD Automation CDB-50? We currently have a Micron 2 (1997 build). We are using it for small batches of flip chip. We use the waffle pack feeder not the wafer loader.

Grant, I just have one question. Why would you go from a Mydata machine to a Fuji XP? You seem to be sacrificing component range for raw chip output. Wouldn't one of the multi-function machines (0201 - 45mm with similar speed) on the marketplace

We conformal coat our boards and get pretty good coverage along the edges of BGA. If you need coverage along the edges and are not getting it, your supplier may be able to recommend a different material or application method. Most often, underfill

There's a fair amount of information on underfilling CSP and flip chip in the web. Look here to get started: * http://www.asymtek.com/news/articles/2002_globaltronics_csp_and_fcuf.pdf * http://www.smta.org/knowledge/proceedings_abstract.cfm?PROC_ID

when you talk about stencil design, what would you recommend for aperture size on fine pitch if the customer insists on hasl finish on fine pitch devices? i usually use a 10% reduction on everything we have been using ( 16mil pitch and upwards and 0

Another thing : Make sure that there are no other mags plugged into the machine while you are trying to trouble shoot slot 3. I have seen shorted vibratory ID chips mess up other magazines up in different slots. For instance : a shorted vibe in slo

Is it possible your board is warping and skip plating? Have you run a lev-check? What does your contact patch look like? Do you have ice cikles (spelling???) or solder "flags". IF yes, your flux is consumed or nonexistant. What is your dwell time

Then he's a very naughty man! Advantis with Lightning head: Chip Accuracy +/- 68uM @ 3 sigma CP643: +/- 66uM @ 3 sigma CP842: +/- 55uM @ 3 sigma I know specs are just statistics but both our Fujis & Universals still calibrated to well within the m

Hi, Actually the sales guy from Fuji recommended to us XP because of the speed and feeder load. We get 100 feeder positions per chip shooter, so that's nice, plus they are CP feeders, so there is a lot of second hand feeders. I saw the NXT in Taiw

IPC-7525 is a document that provides guidlines for the design and fabrication of stencils for solder paste and surface-mount adhesive. This is the first time this important information has been collected and published in an industry consensus documen
