Re: removing SM ICs

Pen of course is acceptable but more expensive.? The stuff lasts a long?time, probably a couple years after expiration and a bottle goes a long way.? So I use a QTIP or one of my insulin syringes (which in most of the US you can buy over the counter at a pharmacy) instead of a pen.? When you mess it up, throw it away.? No cleanup needed.? I prefer paste for leaded devices when needed but it makes a mess with SMT unless the pads are huge like on voltage regulators and power transistors.? But the liquid works fine on leaded parts too.? Just harder to use.? If you have not tried it on SMT parts you should.? It's amazing the first time you roll that ball of solder and it works.? Really once you get it down, you loosely tack a lead in one corner, straighten out the part, loosely tack the other corner and then roll the ball from the opposite?side from the tack towards the tack on all sides with the iron.? You can make it look like a pick and place that way... Fred W0FMS? On Sat, Oct 30, 2021, 6:43 PM Glenn <glennp@...> wrote: Totally agree with Fred. |
