    you could put a strip of spring-metal on one corner mounting hole to press the thermocouple to the plate

      Just jam the thermocouple in the end between kapton tape and profile.

          As they are all touching the ptc should be the same as the aluminium.
          The flat parts are also colder than the middle, so upside down the flat surface has an uneven heat anyway.

            Ok, did some testing. 3 minutes 30 seconds to 215C. Top temperature around 330C or so in another minute or so. It bounces aronud a bit between 225 and 235. I had one measurement around at 239C. I ran it on top of a marble slab, there were reviews that the feet get hot, and I believe them.

            Hard to argue with the price on this one. I'll have to go through my projects and see if I need to reflow anything.

              i put mine on threaded standoff posts so it is a good inch from the table

                Mine rests on a silicone soldering mat. I have two large heatsinks that are the same height that sit either side to provide better support for strips. I have also got disc cut from the insulation for a log burner, good for over 1000c

                  Were these test at 120 volts or 240 volts which version do you have that you did testing on

                    pretty sure he used 120v, because at 240v they heat a lot faster than that!

                      Yes, tested at 120v.

                        How are people getting the hot pc board off the plate? My luck, I would bump it and have parts all over the place. There needs to be a lift or something?

                        clearchris, can you measure ohms cold and hot of the plate you have. I ordered one 100V for $9 and will compare when the slow boat comes in.

                          i have an inline switch on mine that was intended for a table lamp.
                          i just power it off and let it and the pcb cool together usually

                            I do strips, so there is extra support both sides of the plate and then I lift it with these. https://www.aliexpress.com/item/1005003324153934.html

                              I can't measure right now, my meter is across the country. I may pick up a cheap meter in the meantime though.

                                Even an aluminium foil paper sheet would provide much better results.
                                Place the sheet over the heat plate, leave good margins, place the strip, do the work, lift the strip picking up the aluminium foil paper edges.

                                If quick cool down isn't needed then follow:

                                  Those gloves work great. I'm moving a hot pcb a few cm. I'm. Puzzled how you can tell me thy don't work when they work great?

                                      But if those gloves work great with pcb boards there's possible answer to your question @redwire

                                        Yes, mainly aluminium with the occasional fr4.

                                        Whilst the OP and others might claim they are new, I've had mine since 2018, how long does it take you to find an optimal way of working with a tool ?

                                          Agree, LED strips and tools to work with aren't new

                                            by Azurain
                                            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...

                                            Repairing cheap chinese Led bulbs

                                            Hello,

                                            I'd like to try to repair these corncob shaped chinese bulbs with tens of Leds on them.

                                            I know they're bad quality and fail fast, because of the Leds or the capacitor(s).
                                            So I plan to try to replace the main capacitor 15uF-400V with a good quality one.

                                            I've used in the past some capacitors of this eBay vendor which is well known on this site: egekecu. I'm still daily using a monitor I repaired with his products.
                                            I know it has been said he sells good and real brands but outdated capacitors. He's actually 3 times cheaper than RS-Online...

                                            Hello everyone, next I have the following problem with the Sumsour 8586D 110v dual station I bought it a year ago and it worked wonderfully, now it presents the H-E error on the soldering iron side, the hot air side works correctly..... I disassembled the soldering iron head because the manual tells me that this error is due to ceramic resistance problems, in effect, I measured it and it is open, I bought a new one that is working verified in a soldering iron and nothing.... The same error continues, I proceeded to open the station and check visually, I found a totally damaged 1R00 surface mount...

                                            Guide to transplant MEC1503 EC chip and EEPROM reprogamming for T14s gen 2 and X13 gen 2

                                            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...

                                            help SG2701B01-7 panel chinese, would this integrated circuit be equivalent? Chinese IC CS601C regulator.

                                            Hi, I'm repairing this Chinese SG2701B01-7 panel. There isn't much information about it. The original part for the panel is a CSOT CS601C regulator. I can't find anything commercial on Aliexpress; there's only the CS601 without the final 'C'. They claim it's a variant. But will it be compatible? Well, my diagnosis on this screen is a video problem; the image is practically black, although there is HDMI communication. The LED light is on (backlight), but there is no VGL, no 3.3V, and no VSS. It seems that this IC is the one controlling these voltages. The monitor worked correctly for a moment and...
