We are starting up a new clean room for SMT production and wondering if anyone is aware of any guideline for operating humidity and temperature ranges for the room. We know that the MSD's will prefer it to be dry and cool. However, there are other f

Hello EveryBUDDY ! Sorry if my questions sounds too naive!!!! I am into Mobile phone repairs and have not been hearing much about "LEADFREE" soldering till now. Browsing thro' this forum and various SMTNET newsletters, i find that this is one of the

Good morning Ken, Thank you for your feedback. Just as a clarification, SMD stands for Surface Mount Device. Although my end product, in this case, is a SMD, it might be also referenced as a board. In the other hand, what I get from your feedback i

It depends. If it's a current desing that can't be changed, we go outside the box on any issue to see if we can build it. Then it all comes down to time versus dollars. If it's a new product we offer suggestions to the customer and try to bang out

For reflow, bump up your profile as hot as you can go as allowed by your paste manufacturer will allow. If you can change solder paste without too much red tape, several solder paste manufacturers make a transitional paste designed for mix of lead a

The final reflow profile really depends on which of the components are Pb-Free (such as BGA's) and the lowest temperature limit of the components. I'd be glad to share with you some ideas for solving your particular issue. Please contact me offline

Waving the board will sweap away the crud of black pad and to produce a solderable surface, but this surface may have too much solder and may not be very flat. This can create problems when printing paste and placing and soldering components, depend
