Hi Technetters,

I understand that the 'anti-tombstone' solder paste contained 0.4% silver.
Some people told me that the melting point is 179 deg.C and other said it
was 183 deg.C.

I am wandering which is correct.

And what about the percentage for the tin & lead, whether the tin makes up
63% of the alloy & the lead consists of 1.6%, or some other number.

Thanks.

Regards,
Poh
