Re: which idea to socth the ffc cable in place
ur best choice is to buy ffc Cable connector, but important to know the pitch and how many pins. to avoid melting Clean the board of old solder, apply leaded solder and heat to melting pont Before attaching the connector. That way u have the pins left to solder.
Other choice is to remove old connector, solder the Cable then directly to board after stripping Cable end (using solder iron to strip the plastic. -

Find a thick enough plastic cut it to size and use it to squeeze cable connections in place in the connector.Comment

Problem
This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached.... -
This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.
There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as... -
Hello everyone.
I have come here with a rather specific question. I was given a Dell Latitude 7420 laptop with a busted screen, and wanted to see if I could refurbish it into my daily driver. I wanted to experiment and see if a 2-in-1 display would work as the chassis of the laptop and 2-in-1 7420 looked identical. I threw in the display and my hypothesis was correct, however, I was greeted with a locked BIOS and since I didn't know the password, I figured I'd try to unlock it somehow. I bought one of those POGO pin probe things for my CH341A programmer so I could read and make... -
Hello, I'm a beginner for micro soldering. Right now I have some difficult to solder a qfn 20, I guess I put too much solder on the thermal-ground pad, the result is a corner of chip wich don't touch the board (last try).
I use a wire solder with hot air, I tin the board and chip before with iron and I use good flux.
I will have to solder a LVDS connector (40 pins, laptop pc), I saw a solder paste in seringe, good quality (it does not scatter).
See the test :

Hi guys.
I'm working on my first board reballing.
It's iphone 12 pro max and I made a mistake(s), but now to learn something, I hope.
Either I overheated the board and two ics fell off on it's own, or I clumsily took of top board and knock them off. Adrenaline was high at that moment so I do not recall best.
I repaired the damage by putting these components back in place. In some moment I begin tinkering about my future steps and about the fact that I have used low melt solder (138C) to put those components back. My line of thoughts was something like, if I use same solder...
