For pads such as a d-pack... what is the effect on heat dissipation of leaving the unsoldered portion of the pad exposed metal or covering with solder mask? Is there a percentage of heat dissipation that is inhibited by covering with mask?

I'm looking for the user manuals and the service manuals, and if it's possible some advice to start, I had just purchased one, but I don't know how to do. Thanks

You might get more answers if you write something that shortly describes the basic of your problem and possible equipment in the Subject area, instead of "Strange problem". See it as a Topic of the contents of the thred. I hate when I need to open up

Hello everybody, What is considered "high frequency" when we talk about possible issues with NO-clean flux residues and product's application? I appreciate your help on this... Have a good one! George

Good morning, What is considered "high frequency" ,.i.e. Mhz,GHz,etc., when we talk about possible issues with NO-clean flux residues and product's application? I appreciate your help on this... Have a good one! George

I had problems with very simple timing circuits in the kilohertz range with leadfree NC solder pastes. Never saw the problem with lead NC solder paste. Run lead free no clean and clock was off. Run lead no clean and clock was right on.
