WSOL and solder pot

Electronics Forum | Wed Mar 12 12:28:52 EDT 2008 | operator

I recently witnessed a process in which the solder pot operator used Techspray WSOL water soluble masking to cover the areas around a connector that was to be soldered on the solder pot. He did not wait for the WSOL to cure. He soldered immediately.

If the mask is not cured and is coming off in the pot I don't see how it is protecting anything. If you want to mask something fast you need to use tape not liquid mask that requires cure. My $.02.

The way it works is the liquid solder immediatley cures (or should I say burns) the WSOL where ever it touches it. This hardens and keeps it in place and protects whatever is under it. Some of the WSOL falls of in the pot. I am suprised that the burn

Poor training. Don't blame the operator, he was either shown this or left to his own devices. Be the better man and provide him a better process. Regular old peelabale solder mask would be a start.

ESD flooring and footwear

Rob is right. ESD flooring is "Conductive" which means it can drain ESD from the body. But if you have an insulated shoe, it does not good, the ESD remains on the body. Now if you wear a smock, then you can rub ballons in your hair and touch any

I witnessed this at our sister company. It seems to be their standard process. It is not my place to interfere with their processes. I was just curious if there was any chance of brittle solder joints or other defects that might be caused from the WS

SPC and Wave

Sure you can use SPC charting on the wave setup parameters to warn of impending problems. Examples of useful points of analysis are: * Dwell * Temperature * Pot analysis Certainly there's a range of other process controls that could be monitored.

thomas, why isn't it process control, you cant just think that because you've set up your machine properly ( pot temp, wave height, pre-heat etc etc )that everything is going to be ok, there are other factors that you wont find with wave riders or

Material Ageing and Storage

Electronics Forum | Thu Feb 22 04:00:02 EST 2001 | Scott B

We are increasingly being asked to store components for longer and longer periods which we know through experience leads to reduction or total loss of solderability of the parts. 1) What is the industry accepted shelf life of tin/lead plated compone

Conveyors and bar code

Electronics Forum | Wed Aug 23 14:59:32 EDT 2006 | bill

I�ve been lurking on the forum for a while so I will take a stab at this, mainly because there is no answer I take it that you have a variety of boards being produced at the same time and are in fixtures so the conveyors don�t need to be adjusted, a
