Davef, thnx for your reply. Sorry, forgot to clarify "our normal soldering process". We use standard Sn/Pb & SAC305 for our non RoHS & RoHS requirements. We only have a "No Clean" process, no aqueous flux is used. Hence our flux will be mild. As susp

Hi Ryan, Standard shelf life for FR4 Non-RoHs & Rohs material with HASL or Lead Free HASL would be 12 months + in a controlled environment. on all RoHs materials over 6 months, we would suggest your board shop run a solder ability test before ship

You should have no difficulty with QFN or QFP parts when using non-RoHS solder. The QFP's are most likely to have tin plated leads and the metallisation on the QFN lands the same, or ENIG. Check the component part datasheets to verify the plating an

If you are in standard specs, don't even mention it. THe RoHS thing in electronics becomes more and more annoying. I haven;t seen people taking out PCBs from their electronic devices and start to chew them. So it was ok to use gas with Lead for deca

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 fu

How fast do you use your OSP boards? We don't use them but if we did I would want to try and use them the same day we open them. They are cheap but do not store well. Tin/Lead paste spreads much better than ROHS paste. If you can not always reflow

HI all, i have 2 omniflow 5 zone reflow ovens would these be suitable for rohs compliance also 2 iemme 760 reflow oven with 4 upper zone and 4 lower zones would these be suitable also any feed back would really help

we are using convection ovens and we face the issue when changing from Pb to RoHS but also even when change top side to bottom side if the diference on the profiles needs to go from a high temp to low, we are opening the hood but we would like not to

Hi. Alpha metals recently informed us of: Alpha OM-565 low temp solder which they note is popular with pin-in-paste process of through hole parts so that we can solder inside of our SMT oven (1809EXL). We commonly use ROHS DSUB connectors (9 to 78
