Hi I'm trying to remove a eeprom but for some reason the solder will not melt iv tried it at 400c with hot air and will not melt any help will be grate

[@LMAutoRepairs]

I had to swop the eprom over onto another set of speedo clocks on my vectra c, so It would diaplay the correct milage. Worked a treat considering it was my first time desoldering and re-soldering a eprom. Great video as always.

What temperature is your heatgun to melt the solder?One i bought was a 500 degrees centigrade one,eeprom won't budge????

[@LMAutoRepairs]

Probably lead free solder, but, at that temperature should do... Maybe that 500 reading is incorrect... Use some lead solder to mix with the lead free solder using the soldering iron, then should easily come of... 👍👍👍

I noticed on first technique you applied the flux as a glue to hold epprom like chip in place before heating the legs up again. I am reading you said you need to clean flux off so you get a good read. I am going to attempt to replace the epprom chip on my TV and want to know if first technique will work. How do you clean it if you use it as glue?

[@LMAutoRepairs]

I don't use it as a glue... that is just the flux consistency... you can clean using alcohol... Thank you for watching and for your comment!

Use flux to help out... if the pcb is lead free, with the soldering iron to mix some lead solder... Another thing is, if your hot air gun temp is not correct, or you are keeping it too far from the chip... Hope that helps... Thank you for watching!

Thank you. You just earned another subscriber :). Can you make a short video to solder the eeprom with soldering paste with hot gun. I just need to make sure the right temp and which paste is the best, because I just keep burning the eeprom legs :). I bought some chip electronic stuff, just to practice with eeprom soldering. At the first try, I did an amazing soldering, it was the ECM of 2001 Lexus RX300, but I don't remember which paste I choose T3 or T5 and what temp I choose. Since then, I keep burning eeproms. Anyway, Thank you

[@MrFluorescentify]

Conor Cousins they dont go anyway around , there is always a mark position pin 1 side on chip but not always marked on the pcb so mabe you want to make a sign on pcb when desolder it.

[@LMAutoRepairs]

Robermon YT Absolutely correct! I mention that on other videos... 👍👍

[@MrFluorescentify]

You have to mention that is much better to desold and sold by hot air when you have to test a lot with the chip, if you use solder iron more times you risk to damage traces because they are very thin.

[@LMAutoRepairs]

Robermon YT I don't even do that... when I predict I need to desolder and solder many timed for example, an eeprom, I just solder an adapter... 😋 But yes, you are correct... this was only a brief explanation on how to to do it... that's all...👍👍👍👍

[@owaisakhter2673]

Video was good but you have applied heat on pins longer instead of doing it once. You may remove your bulky solder from pins with help of desoldering braid / solder wick. That is how you can apply less heat at once and remove bulky solder at once. After you may drag your soldering iron tip on pins only one time with little solder on tip. I usually do this technique and it's better way to not apply heat repeatedly on same pins or area.

[@LMAutoRepairs]

Different techniques, same result... This was just a brief demonstration... Of course depending on what you are doing, you need to apply more or less heat, remove solder with wick first, etc... Thank you for watching and for your comment! 👍👍👍

It’s best not to clean the pads with desoldering braid. Using braid improperly is the reason pads get ripped off boards. Instead use flux and add new solder to pads. There’s no reason to completely remove solder from pads.

I agree to disagree... If you use the correct temperature and technique, no way you are going to rip the pads off... if it is happening to you, you are doing something wrong... Thank you for watching and for your comment! 👍👍👍
