    Help with this FPC connector 820-01521-A

    Hello everybody. Working on a donor board of a 820-01521-A and kinda got stuck while removing the USB-C FPC connector. I am now wondering how to properly remove it from the board (without damaging it) and what about putting it back on the motherboard? I thought of applying heat from the other side of the board in the area where the FPC connector is located, but there is just too many components that will shift around when the heat is applied.

    Any help will be appreciated!

      Remove it with an IR preheater. Best way to pull things from these boards. The PCB is too good at sinking heat to use traditional "heat below board" to remove these connectors, and the inset pins make applying low-melt solder to the pins impossible. Preheater is 100% the way to go.

          Thank you, will look into that!

              Help identifying connector for ASUS 4090 Strix RGB LED connector
              by 5mall5nail5
              Hi All -

              I had replaced my ASUS 4090 Strix cooler with a waterblock and put the stock cooler on the shelf. Was moving it and snagged my sweater on the connector and pulled the wires out of the pins on the RGB connector. I tried to get them back on but its too small so I opened the stamped pins and tried to solder but its not a good repair and the wire broke on reinstallation.

              Looking to replace the connector on the cable side and get pins to crimp onto a new cable. Bought random JST and such but nothing is correct. Can anyone help identify the connector and possibly matching...

              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....

              Mounting and Handling Guidelines for TO220 TO220F TO247 Cases / Packages

              The TO220, TO220F and TO247 are the popular packages for power devices because of their versatility and ability to dissipate moderate amounts of heat. This application note describes the basic guidelines for handling power MOSFETs in TO220, TO220 and TO247 packages shown in Figure 1. Please note that only mechanical and soldering guidelines are covered here. Additional precautions are required for isolating high voltage rated devices to meet safety regulations.

              Securing a good thermal interface between...

              MacBook Pro Mid-2014 A1398 Retina LED Controller Connector [First Repair (Disaster)]
              by bussincaps
              Hello All,

              tl;dr: minimal electronics experience and my first repair, lifted 8 pads off the laptop display LED controller board when attempting a connector replacement, options are attempting pad repair or jump wiring.

              Laptop Model: MacBook Pro 15 Mid-2014 Retina, A1398 MGXA2LL/A
              eDP Display: Samsung LSN154YL01-A02, assembly sold as Apple part 661-8310
              Soldering Equipment: Hakko FX-888D w/ T-18 tips (Chisel, Conical, Bevel types)

              I needed to replace the 30-pin I-PEX Cabline connector (labeled J8300 in the Apple 820-3662 mainboard schematics),...

              Toshiba Satellite M50-A keyboard connector on LA-A481P motherboard
              by michhak
              Hi guys,
              i have a damaged keyboard connector on my older Toshiba Satellite M50-A laptop. I know there is LA-A481P motherboard. In attachment pictures there is a real looking connector and i also found a schematic to the connector. But i need help with finding a real electronic part to replace the damaged connector. e.g. on aliexpress (or different page).
              It is 34pin connector and the length from pin n.1 to pin n.34 is 26mm. So it means a pitch length is 0.764 mm. I have seen connectors with 0.5mm , 0.7mm , 0.8mm and 1mm pitch length. But not with 0.75. Is it some special custom connector...
