You need to find out what is not compliant about the part. Also some parts can be compliant even though they are not stated to be. Even if the leads had a tin lead finish it may not be enough to make it not compliant. Anyways there is not any body in

If you are using lead solder (SnPb) HASL is a good choice. If you are using lead-free (RoHS compliant) solder then I would recommend Immersion Gold (ENIG).

OSP finish is the big issue here. You almost can not get 100% coverage solder on OSP with 1 over 1 aperture stencil. Reconsider solder coverage requirement in this case. Check your peak temp in profile may help a little.

Hi CP, From a PCB manufacturing side, all of our product is Lead free / RoHs compliant if it has a surface finish other than Hot Air. To be ROHS compliant and Able to with stand Lead Free Assembly, this is where the board house would need to switch

Looking for advice on soldering lead free paste to a board with very heavy gold plating, In my opinion, Gold contact surfaces are often used on circuit boards with membrane switches which is a choice of technology for industrial, commercial and consu

I have a through hole product that is currently built with HMP solder(93.5Pb,5Sn,Ag1.5). We then dip it in 60/40 SnPb to give a solderable finish as HMP tends to oxidise. We need the HMP as our Customers solder through reflow ovens. Some customers w

Hi, Is anyone out there already testing components from their suppliers for: 1. to determine if the components vendors are slipping LF finish components without notifying the end user so, eventually these end up in a leaded assembly for a exempt pr

I concern about the Through Hole soldering as well. Currently, we have encountered some problems of Multilayer from Through Hole soldering. The root-cause is probably related to PCB Finish, machine setting, Thermal relief Pad or hole and something e

All, I am currently finishing off my PO for solder bars,paste,solder wire and Flux for the changeover to leadfree. Surely the company is not expected to take the full hit on this cost alone? I know there is some funding available for this but as f

So the moral of the story is..... these SAC305 BGA's were accidentally mixed in with a Leaded process, the profile couldn't get hot enough due to Tg and Td constraints on a known good QFP on the same board, and consequently, the whole assembly fail
