Hi, I was informed that our supplier of PWB's will start using RoHS compliant Materials but will still support HASL. And these are the materials that they will use: Standard FR-406-408 High Temp - polyimide, cyanate ester High Temp - Roger's, Teflo

Hi All, this has not happened but I would like to know what the possible effects would be if we ran a non-rohs pcb (hasl) thru a leadfree Process. We have a customer who cannot confirm if the board is rohs compliant or not and we are waiting on con

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

As Russ said, you aren't responsible for your customers product being ROHS if they didn't request it be built as such. As a CM we build what the customer requests. If they request a ROHS board and supply us with a ROHS bom, but ask for a HASL board,

I need to solder SAC/HASL PC boards in a NON ROHS process (Tin Leaded solder paste and profile + Tin leaded components) Can I do that?? Regards, Eyal

So, your scenario is: * Lead Free Solder Paste * Lead Free Reflow Profile * RoHS Components * Non-RoHS (Sn-Pb HASL plated)PCB If that's the case, you should be just fine running your Lead-Free process. There is literature on the topic of lead

All, We are a contract manuf. for electronics. Since changeover to RoHS we still have customers due to one thing or the other telling us to run Non-RoHS. They are not exempt. What do we do ? do we tell them that we are not running their boards and

I almost forgot; If the pcb have HASL (Non RoHS) surface finish, then big fine pitch QFP:s could be shifted during reflow, beacuse of the un-even pad-surface... We have been trough that scenario also... But step No.1 is to make sure that the componen

Thanks Dave, From what I remember a lot of components went away from Silver Palladium to "base metal" terminations because of the difficulties in continuation of supply & stability of price. (Something about being mined in Chechnia or the Congo?) W

Hi, we're currently running a design with a fairly simple BGA. The problem we're running into is poor solderability (cold looking joints, high voiding in the BGA). All of this on a know good oven, with a known good thermal profile. I'm guessing it
