No experience with low temp solders for PIHR but we do use standard lead free 245-255 peak profiles on high temp connectors frequently. Honestly the added cost of the high temp connector pays for itself in labor. I almost always use oversized apertu

Actually cleaning of PCB's may see a resurgence with the lead free movement. Higher temps and more aggresive fluxes might need to be clean depending on your board and process. In addition Wave soldering solder pots (in some cases machines) may have t

Hi everyone! I am looking for a lead-free solder that will survive a customer reflow of 260C. I am currently using SN10/Pb88/Ag02 but the reflow temperature is to high (320C) for the FR4 boards that we have. I know there are higher temp FR4 boards

Hi, Now in my wave the PCB TOP Side temperature before WAVE is 110 - 115 DegC and the Peak temp in the wave is 240 - 245. These informations are for an 63/37 Alloy. What is the PCB TOP Side temperature and the peak temperature for Lead Free Wave Sn

OK guys here is the skinny..... We need an oven that can handle lead free temps without slowing the belt speed under 28 or so in. per min. BTU tells me that they don't recommend an oven that maxes any less than 350 C. Is anyone using a paragon 150

Are you running a lead free process? If not, have you identified these as lead free components? If so, have you increased the temps in your profile to accomodate that? After that, I'd look for a AgPd (silver/palladium) or some other such PITA platin

At my last employer, we ran a number of tests to make a "Hybrid" profile work (same profile Joe lists) . It worked great for everything but BGAs. The problem (6 months ago) was using parts not rated for lead free reflow temps. As the market fills wit

I face a problem where the components termination is non lead free but solder alloy is lead free. Thus i am using hybrid reflow profile. The specs for the reflow profile i am using: reflow temp. 120 to 160 deg C; time 90 to 120 sec. As for the pak te

Jimmy, We've been soldering tin plated components and Ni/Sn (100% Tin) boards with leaded solder in the 80's in hirel and military applications. We never experienced reliability issues with the mechanical or electrical properties of the solder joint
