Is anybody out there using Sn99.3Cu0.7 for wave soldering? How does it look. (Cost is about the same as eutectic 63/37).

Dr. Lee, For lead-free wave soldering, we are recommended to use SnCu0.7, why not 0.8 or more ?? Since SnCu0.7 has eutectic melting point at 227 deg C, does it mean with more Cu or less Cu, the melting point will be higher ?? Also, in lead solderin

Dear all, Recently we encountered some functionality failure when using lead-free component(Sn99.3/Cu0.7)at SnPb(Sn63Pb37) wave soldering process. Can lead-free component use at non-lead free process? Any input/idea are much appreciated. Rgds

I ask for advice on starting wave soldering machine. The soldering machine is not new. Are there guidelines for properly loading solder into a bath and more. I also ask you to recommend an alloy. What do you think about Alpha Sn Plus 07 or SN100C(Sn

Hi does anyone have any experience of running Sn 99 Cu0.7 Ag 0.3 solder in their waves? Also is there any reliabilty data available? I think it may also be called C7A3. All I can find is a brief mention in a table in IEC 61190-1-3 2004, and on a pr

The 99C is the part number used by manufacturers for the Sn 99.3% Cu 0.7% Alloy.

Although greatly publicized and many papers on the subject, I wish to hear experiences from the field from professionals who have migrated from SnPb wave soldering to PbFree wave soldering. I am being pushed by one of my largest clients, an internati

hi, NEMI recommends separate solders for reflow sodlering and wave soldering. Reflow soldering- Sn-3.9Ag-0.7Cu Wave sodlering- Sn-0.7CU Wavesoldering- Sn-0.7Ag What will happen if a mixed technolgy PCb board containing both through hole and surface

Here are some general rules for lead free wave solder: Noble aloys will cost more. Period. The cheapest metal on earth is lead. Costs can only go up in Lead Free. Consumer grade and class 2 electronics will most likely use Tin / Copper for wave.
