| 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've been using a newly installed DI re-circulating system. | It's been a big headache. Mostly understanding what causes our resistivity to be unpredictable. I think I've got a handle on that part now. The system consists of a Carbon,HMR(chealet),

| Hi Folks, | This is my first surface mount board, so I asked our assembly house for some tips. They said only passives on the bottom side-preferably no smaller than 0805, 0603 only if I have to. I would think that an SOT-23 would be OK on the botto

John, SOT 23's on the bottom side is no real problem...as long as you get the orientaion to the wave right and you remember to increase the pad sizees to allow the solder to get to the pads. Soldering with only one wave would be trick as Vinesh sugg

Thanks guys, since I have no control as to who makes the board (probably the lowest bidder), I guess I'll keep the SOT's on top. Thanks for your help, John | John, | | SOT 23's on the bottom side is no real problem...as long as you get the orientai
