Nice idea! I dont plan to remove these mosfet drivers unless I blow up the board again, except of course the way things happen anything is possible.To me, if you want repeated or often remove and replace, I would tend to use a ZIF socket?
You put molybdenum grease? In the contacts? That´s a terrible idea. The contacts should be bare and clean and definitely not greased.I put a little moly grease and they slide right in, and they come right out, no troubles.
Also I find the leaf contacts in the cheap ones sometimes dig into the tin plating on the pins - when you try to take the chip out, it rips out the contact leaf.They are better quality and generally you pay a little more for machined pins.
Grease is probably best avoided, especially if there's a cooling fan - it'll stick to every bit of crud that convects/blows through the equipment.Ok, I looked at it and it is Valvolene synthetic wheel bearing grease, not particularly moly grease.
They went in smoothly and are tightly secured, they wont be falling out. Just a light smearing of grease only on the pins.
I had been reading how some people bend pins and find these sockets difficult to insert chips.
I had no troubles at all.
There is not enough grease to attract any dust. Just enough grease that the DIP leads can easily slip into the socket,.
Yes. one reason I bought that particular socket was it had a higher heat rating, I could imagine it melting when soldering. There are so many different socket choices to make, one I chose had gold flash which I figured would aid in long term connectivity quality. I had read people were complaining about the sockets bending pins, being hard to put in chips and take them out which is why I opted to try the grease. With my limited experience I could easily imagine me trying to push in a chip and the legs bending, then the leg breaking off in the socket. I did have to carefully align the chip legs to the socket as they were spread too wide. Maybe some of the insertion problems is people not being careful getting the legs into the holes? I was also concerned about someday needing to remove the mosfet driver chips if I blew up the inverter again and finding them fretted - stuck - corroded into the sockets.I've never had much difficulty pushing ICs into the cheap sockets, except it isn't so immediately obvious when a slightly bent pin gets folded under.
The big problem is sharp edges on the contact leaves that dig into the tin plating on the pins - it sometimes rips the contact leaf out of the plastic header when you pull the chip, lubricant will actually make that a very slight bit worse.
When I restocked with sockets, I bought only the turned pin type.
Sometimes I get scrap boards to harvest parts from, turned pin sockets most of the time can be recovered intact - the cheap ones are more likely to have damaged pins where they protrude from the solder, these snag as you try to pull the socket and keeping the solder molten melts the plastic header and it collapses.
