Grant, Non of the articles state that lead-free will go away (unless I missed something). I've never heard it being a problem souring lead-free components only leaded components. But I have to admit not being on the manufacturing floor on a daily ba

PB-free Hasl was not mentioned due to the following: 1)Equipment Convertion at the PCB Manufacturing side is expensive. 2)You are subjecting the PCB to Higher Temps than Std. solder. 3)Most PCB Houses are not going to invest in Two Hot Air level

I have been getting non wets on fine pitch QFP packages on random leads during reflow process. I noticed that every time there is some flux residue left between the non-wet lead and the solder pad. No residue was not observed on the rest of the good

I'm no metallurgist but I don't think you're going to burn up lead with a soldering iron. That said, I would surmise that you could pull a lot of the metallization from the component terminations (very likely lead free) and the pads on the board (i

I'm about to begin a job for a customer placing a couple of lead free BGA's/FPGA's on an assembly that doesn't need to be RoHS compatible. So...my question is...should I process this assembly with lead-free solder paste, to accomodate the lead-free

Was wondering if anyone had any experience with Pin Though Paste with a no-lead process? I realize that some basic requirements will need to be met (i.e. Connector to with stand higher temperature, proper lead coating, ability to image, etc.). But,

We are in middle to prototyping a lead free assembly for one of our customers. We are using lead free bare PCBs, consumables and components, except for two ICs which are leaded per the customer BOM. Will the overall assembly be defined as lead free p

"Although some lead-free pastes performed adequately and newer pastes work better than earlier formulations, this detailed experiment confirmed that tin/lead solder pastes wet back to PCB pads better than lead-free solder pastes. Therefore, a more ac

It is possible to vary the length of lead during auto insert. However, it requires software and mechanical adjustments. Universal equipment allows small changes via software program for lead length. To change angle of clinch involves a mechanical a
