Lead Temperature due to Soldering?
Lead Temperature due to Soldering?
(OP)
The absolute maximum ratings for an integrated circuit states that the lead temperature should not exceed 260 C. And in parenthesis it states "Soldering, 10 seconds". Does this mean that the lead can be at 260 C for 10 seconds? Does it imply that it can be soldered with a higher temperature tip for a shorter time and if so, is there a rule of thumb for that time/temperature combination?
Thanks
Thanks





RE: Lead Temperature due to Soldering?
You may also try to cool adjacent portion of the integrated circuit (I suppose bord) while soldering but somehow not cooling the soldering location (use of some heat sink). That will give you at least those 20 seconds to carry out the soldering. Or solder intermittently if possible.
RE: Lead Temperature due to Soldering?
While some of the materials can withstand 260C indefinitely, not all the materials can do that, particularly, plastic packaging, some organic overcoats, etc.
Moreover, even 260C is suffciently high enough to potentially cause/accelerate junction spiking on inputs and outputs.
