SMT Production Floor RH Control | 8 January, 2007

HI Friend, My SMT Production Floor RH reading are 38%RH to 65%RH. It is within control or as per IPC/J-STD or orthers industries standard recommendation? Hope to hear comment from anyone. Thanks!

Good afternoon,

22C +/-2C, 40%RH +/- 5% is a good starting point. I wonder if any standard requires floor temperature and humidity control. Most of requiremens come from solder paste manufacturers.

BR, Pavel.

J-STD-001 makes RECOMMENDATIONS but they are not REQUIREMENTS. Only REQUIREMENT is to make sure your ESD control is adequate if RH falls below 30%.
