Hi. I have to apologize again for getting a bit angry. I have now figured out the issue. It is indeed my new soldering station. It’s an ersa analog 60 that I bought because we have ersas at work and they’re great, but this entry model, despite the similar look, just sucks, at least the temperature control side of it, or the lack of it. Today I found out it even struggles with regular leaded solder as soon as you’re trying to solder pins that are attached to the ground plane. Have to turn it up to 450°C to make it work. Very disappointing as it was not exactly cheap. Or maybe it’s a heat transfer issue like you’ve mentioned.
However I have managed to desolder the display using the hot air station we have at work. (Didn’t know we had one) I’d recommend using one of these. I have never desoldered something with 20 pins so quickly
Also I could solder the lead free stuff with no issues at around 330°C with the higher end ersa station at work, so you were right. Sorry.
BUT, I have encountered another issue. The new display makes my machinedrum’s LEDs go crazy. Yes, even though the display works fine, some of the LEDs light up incorrectly and start to flash as soon the LCD is updated (when you turn an encoder for example). Like the “classic” and “extended” LEDs light up at the same time, or the “synthesis”, “effects” and “routing” LEDs will show random stuff, just to give an example. The machine works fine though.
I was really scared that I messed something up, so being a bit desperate, I’ve desoldered the LCD again and put the original one back in and everything’s fine again.
BIG relief, but still … I have no clue what’s going on here …
This is the LCD I have bought btw. Link to LCD (ABG128064A50-DIW-R)
