Hi, The temperature in the fridge is 5-10 degrees.

Good morning, Solder paste softeners are designed to allow solder paste reach ambient temperature during shorter time period (only 5-10 minutes instead of hours). You are preparing your material in right way. No reason to worry. BR, Pavel

I use Namics 8437-2 for micro BGA and flip chips. Will work for QFN or MLF after soldering. Flows well under gaps as thin as 0.001". Cure in 5-10 min at 150 C. Rock solid product. Is bit expensive. Is from Japan.

Hi everyone!! Is anybody have a chart or rule or standard for misprint. What I mean is if there is a way of saying if my print for some reason a switch 1%, 5%, 10%, etc, off the pad that is not acceptable. Thank you Yannick

We are starting to see a large increase in the use of through board gold plated connectors that require hand soldering with the limitation of .o6" encroachment up the pin. What is the best way to accomplish this? we currently scrap about 5-10% of t

What about when debugging the board I recently saw a case where we damaged a board between - 5-10 cycles of the fixture It's a catch 22 - where you need high force probes to breal the OSP - but the copper is hard surface, not like the solder HASL a

Does anyone have a tried-and-true method to account for machine losses of SMT parts? I remember reading an article once that stated that 5% - 10% of components of certain sizes are known to be lost during placement, and I know some CM's overplan by 5

Thanks Russ. When solder paste is applied, you can't see the pads. Because my aperture reduction is 5% - 10% of the pads. Pads are reduced by almost and up to 20% by the PWB Fab and the paste covers the pad. We cal align and inspect but very hard as

Points to consider are: * Gold plating too thick [SB LT 8 uinches]. [Obviously, we're talking about actual plating thickness, not the specification.] * Reflow recipe improper [SB 220*C 5-10 sec]. A recipe that works fine for HASL needs to be hotter

What I usually do is keep the peak temperature about 5-10 deg C below the peak temperature of my lowest rated component, then set everything else up around that. Worse case scenario is to just extend the time above liquidus (TAL) in 5 second increme
