I used current density 15mA/cm**2 in our Macdermid tin-lead bath for 5
min. and I got 110 uin. with a 67% tin. But when I change the current
densities to 7.5mA/cm**2, I got 140 uin. with a 75% of tinfor 10 min..
My question is will a change in current densities in a Macdermid
tin-lead bath screw up the composition of Tin and Lead?
