grey appearance on solder joints after batch cleaning

Electronics Forum | Tue Feb 11 14:05:11 EST 2014 | dontfeedphils

I can't speak too much as to why your joints are appearing dull, even with the booster. I can recommend a new chemistry that Kyzen has out that I've been running for about a year now. Price is about the same, it can be run at low(er) concentrations

Heller MK3 edge chain maintenance

In general the chains don't need to be heated to 400 deg C for cleaning. In other words, most of the fluxes and constituents in the paste don't collect on the chain and gum it up. Bottom line: the heat treatment is not needed for 95% of the users.

bead blasting conformal coatings

Yeh due to the solvents in the coatings im guessing there is a health and safety risk. Solvent stripping is a lengthy process for the coatings we use and usually means submerging the whole board so not local to the rework. We have a booth with ioni

This is a late reply, but from my experience a really good removal station is one made by a company called CCRCo. They make a micro-abrasive station that addresses all the ESD concerns. They utilize a reusable media that is really cost effective. The

Are there any tricks to cleaning a stepped stencil while in use. There seems to always be paste left behind around the recesses of the stencil. We have tried many different wipe combinations and don't seem to be having much luck with it. The machi

SOT 23 Rework Time

That's a pretty vague question, especially if you count "ID" in the time. In a world where you have AOI or in circuit testing telling you which part has to go, limited thermal mass to contend with and decent equipment, I'd say thirty seconds. On my

Looking for equipment

I am not an objective candidate for a Machine manufacturer selection, I only know Fuji's. But, it sounds like a good fit for a Fuji XP series machine. And of course, I will try to find a good one and install it for a fee. The price of a used XP va

Samsung CP45FV Neo Programming

Electronics Forum | Thu Sep 04 09:05:00 EDT 2014 | JB

Hello All. Another question about programming if anyone could help? We are current placing BGA's and it places them fine but we have noticed it doesn't spot when a ball is missing. We have adjusted the settings so it does reliably spot the missing

Type 3 Solder Print/Squeegee Speed

Electronics Forum | Mon Mar 03 15:44:56 EST 2014 | emeto

with 0.5mm pitch I wouldn't go too fast. Check your separation speed as well as your print area(may be you can drive your squeegees 1-2 inches less). Some pastes like Alpha like very fast separation. so you can win another 2-3 seconds from there.What

One thing to be certain on the spring action of your tools is the direction of travel. With the new black tools the tube can seem normal but the slider is retracted instead of extended. This happens when pulling or installing tips. it is a very natu
