Sometimes you need to break shit to fix it.... Thats why my lawnmower doesn't have a deadman switch or engine brake anymore

Re: dad has 30+ experience but couldn't finish the soldering
what tools do you have, pinpoint on picture what exactly do you need to solder ? A hot air would be of help here....the quieter you become the more you are able to hear...Comment

Re: dad has 30+ experience but couldn't finish the soldering
Those SMD regulators will be hard to replace with just a simple iron, assuming that old Weller still has a decent tip on it....
Not impossible sure, but it's not something a beginner should try on a multilayer board like that - far too easy to ruin it.
Why do you want to replace them all anyway?"Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

Re: dad has 30+ experience but couldn't finish the soldering
The easy way woud be if you have a hot air gun. You need to desolder all 3 or 4 pin of regulator at the same time.
And yes why woud you replace all reg ??...the quieter you become the more you are able to hear...Comment

Re: dad has 30+ experience but couldn't finish the soldering
I am still using the same Weller (I use it for over 30 years) and solder sucker as shown in the picture. I use wide tip PTC7 or PTD7 for parts removing. The trick is to add solder and use flux.Last edited by budm; 10-22-2014, 05:17 PM.Never stop learning

Hi everyone,
I have an HP Elitebook 840 G5 that I am trying to get working again. I've removed the front bios chip (the 32mb one) and have run it through HP unlocker already. I've uploaded and verified the new bin, but am now experiencing an issue that has led me to believe I've been soldering the chip back to the motherboard incorrectly.
Essentially, after re-soldering the chip back into its place and reassembling the laptop, the charging light immediately flashes orange and white and then shifts to a solid white. The capslock and numlock lights blink seven times... -
Hi Everyone,
I bought a Yihua 992DA+ hot air gun and soldering iron unit from a used market.
1. Soldering iron works great
2. There is a burnt mark on the hot air gun handle.
I am a bit concern by the look of the melted plastic. I opened the hot air gun handle and took some readings with a multimeter.
Heating element ~ 75ohm. (Similar reading taken from a spare heating element that came with the unit.)
Thermocouple ~ 1.5ohm. (Similar reading from the spare heating element.)
Reed switch tested ok with a magnet.
From the above test, I can conclude... -
About a month ago we had a transformer jumper wire that burned in two different places between two transformers caused over $200 thousand dollars worth of damage to VFD drives at least 10 of them and a memory card and quite a few power supply as well
Now we have most of the equipment that got damaged back up and running except a feeder that has issues and we are waiting for some parts for
Now we also have another piece of equipment that was blowing fuses on the 110 volt controller switch circuit with the “E” stops and one switching power (24 volt) supply and a transformer... -
hello.
A few months ago,I have purchased 0.1mm Soldering Iron Tip of below aliexpress link,But I noticed that It is totally impossible to use this 0.1mm iron tip in the T12 soldering station
https://ko.aliexpress.com/item/4001275635593.html
Is there any good soldering station which is possible to use 900M-TJ-I tip and have inexpensive or reasonable price in aliexpress?
Any reply would be appreciated. -
Hi,
We continue to struggle with the SEF 551.10 reflow oven. After we managed to start it in october - the topic here -> https://www.badcaps.net/forum/troubl...he-reflow-oven everything promised to be good. But...
While soldering with lead paste somehow goes, but we cannot force the stove to raise the temperature
