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

![]() 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. |

![]() 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

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

![]() 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 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

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: Last edited by megaraider; 11-06-2021 at 09:58 PM.. |

![]() [QUOTE=megaraider;1082744]Working with LED strips... not imo./QUOTE]
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 ? Last edited by diif; 11-08-2021 at 03:48 AM.. |
