Re: Soldering advice.
Either use a higher wattage soldering iron or hold the coil end with a long nose pliers on the component side of the board and solder normal way. I have along nosed vice grip pliers that I use. -
Re: Soldering advice.
Preheat the joint with a heat gun or even a hair dryer. Heat to about 100C and your solder will more easily flow to a perfect joint.Comment

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... -

Hi,
solder joints on heat sinks - how much do they matter? Could poor joints on heat sink cause issues if they are not properly joining to hot ground?
I'm looking at power source module of Panasonic plasma TV and I see many of these having visually poor quality, but could they matter? In general I would guess no, but I saw a video where someone was stressing out the importance of tightening the screws when fastening the power source board specifically for the ground to be connected properly.

I have a Lenovo IdeaPad Gaming 3 15ACH, which has started exhibiting the well-known issues of the Lenovo IdeaPad 3.
All stress tests run perfectly, and there are no performance issues. However, the solder joints are almost certainly starting to fail. If the top two screws on the back are not screwed in, moving the screen results in a BSOD or, in some cases, a slight artifact and freeze. This is a 2023 notebook..
How can I extend its lifespan? Could reflow help?
It has ryzen 5 5500h, rtx 2050, no soldered ram.
Example of the artifacts:

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.
