Depends on your specific application. Can you handle lower reflow temps? Can your parts handle higher reflow temps? What environment will your assembled product have to endure? Lot of different factors come in to play when choosing the right allo

Jacki, Lead-free Cu based alloys with melting point below 210C don’t exist.

| | | | I have a board, 4 spacers needed to be soldered on the board | | | | first with the normal 62Sn37Pb alloy. Then, capacitors are manually soldered on the boards. The density of the board is quite high. If we wave soldered capacitors first,

I mean...there are a ton of possibilities for bridging on selective solder before you ever get to alloy purity. Are the bridges happening consistently in the same spot? Are the leads too long? Can you modify the approach/exit/peel off to address? Wh

We believe that some suppliers replace nickel with cobalt in SN100 to product a shinier, less grainy, more attractive lead-free solder connection. SN100E sales-types like the idea that it is available in paste, bar stock, and other forms; as compare

| We process both tin/lead plated boards and gold plated boards in our surface mount group. I have used Sn62/Pb36/Ag2 solder paste on all gold plated boards to help prevent gold scavaging. To reduce the amount of different solder pastes we have to

We recently started to use wave-soldering. As total newbies in that field, we got successful results most of the time. Howewer, this batch of PCB's had a lot of resdiue, as shown on the picture. Most of it is most likely flux, but on some areas even

| | | We are currently using a 65/35 solder for our wave process but are considering switching to a 63/37 for a substantial cost savings. No one here seems to know why we everused a 65/35 formulation in the first place. | | | I understand 63/37 to be

Michael: Two things: 1. Profile: A. Your FR4 profile will not produce good solder connections on your ceramic substrate. Hey wait a minute, you soldered FR4 at 250C?? Ceramic is a themal sponge. You'll need to play, but it should be easy compare

Hello Could somebody inform us about real consumption of lead free solder alloy SN100C on your wave solder process. We do not use some antiaxidant and had had alloy consumption about 1 kg per hour. What is your experiance? All sugestion will be well
