110V 850W Soldering Hot Plate LED Microcomputer Electric Preheat Soldering Station Welder Hot Plate Rework Heater Lab 200X200mm Plate

Does the job

It's great that it heats quickly (just a couple of minutes to bring the boards up to 400C).But it takes a long time to cool down. That will not meet standard reflow soldering profiles. So I need to carefully lift mine with pliers and move it to a silicon pad to cool, along with some added airflow.The temperature setting as shipped is not accurate. You need to calibrate it with an external thermometer placed on a PCB on sitting on the plate.1. Press SET button2. Up/Down arrows to set temp to desired degrees C (NOT F)3. Press Set button4. wait until red temperature on top matches set green temperature on bottom5. calculate difference between that and your external temperature reading of your sample PCB6. Set the temperature offset (permanent):a) HOLD SET button for 3 sec.b) tap multiple times until you see SC on topc) use Up/Down Arrow keys to set temperature offsetd) wait until display times outNow test again and make another adjustment if necessary. You can set either a positive or negative offset.(Mine was negative.)

Works good

Have not really used it a lot, just to repair phones - needed 70C and 80C temperature. But i also tested how accurate the temperate us up to 280C, and it does stay nicely within +- 1C. Measured with a digital thermometer that i attached to the middle of the surface with some CPU heatsink compound paste. I corrected the SC temperature offset in the configuration by 1C though.It does take a while to get up to temperature.

I like the Soiiw 110V 850W Soldering Hot Plate LED Microcomputer Electric Preheat Soldering Station. It is not very accurate, but it gets hot enough for me. Mine shows about 24C lower than the setting temp when set to 200C. The most I will probably ever need is 600F, and it gets that hot easily. For me that is acceptable for the price of the unit.Electronics Repair is one of my hobbies, so I'm pretty sure that I could take the unit apart and make the temp more accurate if I needed to. But I use my Brymen 869s or Fluke to measure the temp anyway, so it isn't that big of a deal for me. I went ahead and gave it four stars on accuracy. Your unit may be more accurate than mine.

The unit seems like it is well built, with a nice fly-cutter finish on the aluminum plate, but it took a long time to come up to temperature. I found a resource online with some tuning parameters and after plugging these values in it comes to temp much faster without overshooting.The measured temperature on the controller is for the aluminum surface, so you might want to put a scrap pcb on it and measure the temperature of the board to get a better understanding of what is happening at the pads.The boards I need to rework have some through hole components that keep the board from setting down flat, so I use a shallow pan with a thin layer of sand to transfer the heat.

Surprised how well this works, it made it quite easy to use a solder paste template with my boards.The only downside is that it does not have any reflow curves, and heats up a little slowly.

Made several circuit boards on this. With proper (manual) control of temperature ramp up and down, the solder paste melted and made perfect connections. You just have to be careful to use the temperature profile for the paste you use and not overheat since you can stress the components on your board unnecessarily.
