New Reflow Oven?

Electronics Forum | Thu Mar 31 10:22:57 EDT 2011 | swag

We are going to buy a new reflow oven. I'm currently comparing Rehm VXS3150 and Heller 1809 Mark III. Both should meet our needs as far as zones. Does anyone have experience to share for either? Good service from these companies?

Yes Tech F1 AOI and 0402 chips.

I was thinking the same thing. Try turning off your anchors and look at the size of your search and % match you have set. if you are concerned about not catching missing components, try training a negative template.

Thanks Graham that's what I'm thinking. I'm gonna have to steal this oven for a while. Thanks again.

Hi, I am process engineer in PCBA factory.I have a question about gold plating on BGA.I want to know difference soldering performance between gold plating electrolytic and ENIG.Many thank for any idea.

obtain XY data from solder pad gerber drawing????

PROCAM is intended to extract Centroid from the raw Gerber only. You just need to have 2 layers (paste or mask layer - to identify pads, and silk layer - for reference designators). Centroid is the output of PROCAM.

Ion Chromatography (IC) qualification

Electronics Forum | Wed Apr 13 09:15:07 EDT 2011 | blnorman

Have used IC for years, but I'm not familiar with that, ROSE maybe. Its a stretch, but maybe R/O/I would be rosin/resin, organic, or inorganic for the type flux being used?

Contaminated ICs

Electronics Forum | Fri Apr 15 18:41:35 EDT 2011 | swarnergictg

We had a similar problem with contaminated leads that was rectified by having a company strip the existing finish and re-tin the leads. After the procedure the leads accepted solder with no issues.

What is the advantage of having zigzag tracks on PCBs?

Electronics Forum | Mon Apr 25 15:58:15 EDT 2011 | davef

There is no advantage for fabricators or assemblers. In high speed memory busses, designers zigzag the traces to keep all of the traces within a certain length of each other.

AOI: Golden Board vs Algorithm Based

Electronics Forum | Tue May 03 21:20:58 EDT 2011 | littlebone

Exactly. And now a day, we are sourcing quite a number of alternative component. (e.g. IC, capacitor...) Template matching may took long time to calibrate the variances too. Desperate to look for cyberoptics representative to have a presentation

I would go with Algorithm based, the reliability is better that I have seen in the feild. Tom Andersen
