RoHS and Non-RoHS products in same ICT Fixture | 24 March, 2017

I have a supplier that want to upgrade all nails on a huge amount of ICT fixture due to test RoHS compliant PCBAs. My thought is that even if there are a very small fraction of residues left on the pins it will never go over the 1000PPM level.

In future we will also have field returns that are going to be tested in the same fixtures.

Do anybody have any comments on this? Could it be a reliability problem or is it only nonsense?

Just 2 cents, lead free flux residue is no clean?, how about leaded flux? how much flux residue it leaves on both types? is there a clean up procedure after wave solder? or is there a wave solder process?

I can't believe there is a topic for discussion. Find a way and measure lead contamination(if any)and prove them wrong. This is getting out of control. Having all the billions of gasoline and diesel engines pumping dirt in the air, together with the coal and nuclear power plants and chemical factories, we are worried about 2ppm lead on electronic board??? Things like that make me think that common sense is not common anymore. Do you know that colleges are teaching critical thinking? Soon they would be teaching Thinking, as it will be a total scarcity.

Restriction of Hazardous Substances (RoHS) bans products that contain a high level of hazardous materials from entering the market like the EU market. If we talk about PCB products - The printed circuit board services – including both conventional and surface mount assemblies – can be done either RoHS or non-RoHS compliant. What I found that lead tinning is for the conversion of components with lead finishes that are lead bearing in order that they be compatible with “lead free” RoHS compatible assemblies. Some industries, such as aerospace, military and medical sectors, remain exempt from the RoHS directive the leaded electronic manufacturing is the most preferable choice.

yeah, I wonder what will be the next? "Do not touch with same fingers PCBs with SnPb and Lead free PCBs as some molecules of lead may stick to your fingers" :D
