LED Light Charge Port Replacement
If you’re like me, you look for every opportunity to pretend that every light you hold is a lightsaber. So, when I had a repair to do on a workshop LED light, I couldn’t help myself, I had to make those noises and pretend that I had Jedi skills. But, when I got that out of my system, I was able to settle down to the task at hand.
This LED light has been used for a number of years in my automotive workshop and is invaluable to me carrying out my daily tasks. Each night I would connect it to a charging jack, the little red light would come on and in the morning it would be green, indicating that the battery had changed overnight. However, I had noticed that the connection into the port had become a little loose and would require a little wiggle to get the charging light to come on. I tried closing the port a little to add pressure on the connection, but this only lasted for a short time.
The LED light sat on my lab bench for some time until I purchased the correct port to install. Disassembly of the light was easy as only 3 screws held on the back cover.
The port design is a USB Micro B with 4 90˚ anchor points.
As a hobbyist, I am always learning, trying new techniques & buying new equipment (just don’t tell my wife 😉). I have always done soldering using an iron & solder. Some time ago I purchased some solder paste and up until now, had forgotten I had it.
One of the major problems I was having was access to the port. It was right next to the main switch with a few other components close by, therefore not allowing a soldering iron to carry out the task. I decided to use a heat gun, which I have used on a number of occasions replacing SMD ICs. I thought this would be easy, but I was trying new techniques using new products as well. After carrying out the repair, I noticed the instructions on the solder paste stated that it had a shelf life of 6 months and must be kept in the fridge……..unfortunately, that was a big NO in each case.
I now realize that I made several mistakes replacing this port but will learn for next time. Firstly, while trying to remove the port, I didn’t realize that there were 4 anchor points & focused on only 2 points. I ended up using my desoldering station to remove the anchor points – a ST-2091 for those of you who are curious.
Secondly, I levered on the port and accidentally tore of part of the track. So far, things didn’t seem to be going so well. But all was not lost! I carefully made up a wire to join the broken section of the track and removed some of the mask so that the solder would adhere to the circuit board.
With that little problem out of the road, I now focused on the reason for the repair. Careful placement of the port was next with some solder paste. As I said, the solder paste had not been stored as intended, so it took some time to heat correctly, but eventually the paste melted and formed a good bond.
After confirming the continuity of the connections of the port, it was now put on charge and the little green LED was proof that the repair was successful.
