EMS-Engineer, Lead free alloys have a very low wetting creep. You probably will not ever get the same type of weting with a LF as opposed to SN 63/37. The question is if it is acceptable. Lead free solder joints cannot be inspected to the same crite

How about this scenario: Need to rework a BGA on a 2 year old board. Originally the board was assembled with Sn63/Pb37 and the BGA has eutectic spheres. Now this package only comes with lead free balls. I believe that the board finish is not idea

A while back we checked out all our manufacturing equipment for lead free capability, we thought our soldering irons would all be fine as they can reach temperatures well in excess of lead free alloy melting points. Last week i was speaking to someo

What volume of boards are you putting through. 1Kg per hour does sound very high but then again it does depend on volume Using an antioxidant is a must with Lead Free some alloys have additions in them to start with but those drop out with use so th

I've had a lot of experience with solder spatter. It's usually related to moisture (humidity) uptake by the paste, or outgassing from plating: particularly Au/Ni. Solder spatter from the plating will change from board-vendor to board-vendor. I shoul

You may want to check out Nihon Superior. Nihon licensed their Alloy to Aim for US production Late last month! The alloy uses nickel and the solder joints look amazing for "lead-free" they rival tin-lead in appearance. Other boasts is that you can

Joseph, I've heard of a lead free solder alloy, Sn43/Bi57 that melts at 139�C and reflows between 160-170�C. You may find the following website useful. Good Luck Scott

Hi, Im doing some experiments and studies on lead free solders ( any alloys).I would like to get some information on a few lead free solder paste manufacturers and if possible their web page adress and contacts. Thanx in anticipation yunus

Sorry theres a mistake on previous question. It should be lead free component termination but non lead free solder alloy Sn63/Pb37. The reflow profile i am using : Soaking temp. 120 to 160 deg C; time 90 to 120 sec. Peak temp. 215 to 225 deg C; time
