Switching to SN100C in wave solder machine

Electronics Forum | Thu Dec 01 05:23:55 EST 2016 | stivais

Rob Just wondering - have you made analysis of your solder alloy on a regular basis? We are using SAC305 but stainless steel parts (e.g. a nut or a washer) dissolve quite quickly.

SAC305 soldering to 58Bi/42Sn

Electronics Forum | Thu Nov 19 02:22:12 EST 2009 | andrzej

Hi, we have an idea of running one side of PCB using 58Bi/42Sn solder to prevent glueing components on other side of PCB when board is on second run through SMT process. I wonder what issues we can meet once we try to use SAC305 when reworking some

Switching to SN100C in wave solder machine

Any lead free will eat a leaded designed wave soldering machine. But SN100c will eat it the slowest, our soldering tips used to only last 3 months with SAC305 when we changed to SN100c solder wire we are having around 9 months tip life. Our wave sol

I've used standard Nikon for years. We evaluated the Mantis and while first impressions were positive but with continued use EVERYONE chose to move back to the standard eyepiece. A lot depends on what size components you're dealing with - when you s

Conversion to no-clean solder paste

To all, This may appear to be laziness on my part, but I need to ask for some advice. We are in the process of qualifying no-clean solder paste to replace or current RMA paste. I have performed qualification runs and extensive reliability testing

Conversion from SAC305 to SN100C

Electronics Forum | Wed Feb 04 03:30:56 EST 2009 | smartasp

Hi All We intend to switch fro SAC305 to SN100C, which has been giving us great test results. Unfortunately we have a technical guy at head quarter, which refuses to accept the SN100C as it has a 10 deg C higher melting point as SAC. I argue besides

Soldering to Platinum/Silver terminations.

Electronics Forum | Tue Jan 30 12:16:47 EST 2007 | pbarton

We are seeing unusual soldered joints when soldering to components with Pt/Ag metallised terminations. At the margin between the bottom of the component termination and the PCB surface there are a number of blowholes in the bulk solder. There also ap

When soldering a component to a board, the solderability protection on the component combines with the solderability protection on the board and the solder to form an alloy. This alloy is unique for that combination of solder and solderability protec

how to remove solder ball on PCB

Electronics Forum | Mon Sep 22 04:59:10 EDT 2008 | fadzil66

I have concern about cleaning solder ball after misprinting paste on PCB, currently use vigon 200 with ultrasonic generate but only 70% solder ball able to remove, Any other method or equipment can help to clean solder ball.

When to trash the solder paste

Electronics Forum | Fri Aug 03 05:11:36 EDT 2007 | coffee_12

I would like to know, if the solder paste for SMT is unpacked (the syringe is opened) and is stocked at room temperature, then when I should trash it. After 12 hours/24 hours exposure? Or any other suggested time? Thanks.
