In this episode of DIY or Buy we will be having a look at reflow soldering plates. I am familiar with hand soldering, hot air reflow soldering and oven reflow soldering and I was looking for a better technique that is easy to pull off and not as bulky as an oven. That is when I found out about reflow plates. So I bought myself one for testing and around the same time a viewer of mine reached out with a DIY solution. So in this video I will test both versions and ultimately tell you whether hot plate soldering is awesome and whether you should DIY one or simply buy one! Let’s get started!

1.The PTC heating plate is made of high quality aluminum and PTC materials, with high performance and high power,30 seconds will be reach about 250 degree Celsius (?±10 degree Celsius), no thermostat needed.
2.Can be used to disassemble the LED light bead and FPC board, can also be used for BGA solder ball.

I’ve made another PID Reflow Hot Plate but this time uisng a cheap aluminum heating plate. We can use the LCD to see the values, control power with a solid state relay and read the temperature witha thermistor.

Any exposed metal has the potential to become live under a fault condition. The heater is connected to the live and neutral, any breakdown in the insulation has the potential to make the heat bed become live. Earthing the heat plate ensures that if this should happen the current will flow to earth either blowing the fuse or tripping the main circuit breaker, protecting the user. In the uk class 1 products need to have an earth, I.e any electrical item that has exposed metal parts that could potentially become live. Hope this helps, all the best!

Great project, however I strongly recommend anyone who wants to build it to implement at least a minimum of safety features found in any consumer product to reduce the chance of electrocution or fire (grounding of all exposed metal parts, one or more fuses to account for common errors, galvanic isolation between Arduino and 220 V net (depending on how much you trust the isolation of the SSR), adding clearance and creepage distance between 220V and 5V net on the prototype board (ideally splitting the board and have a few millimeter air gap), properly mounting 220V lines (I wouldn’t trust hot glue with my live), add some electrical isolation between temperature probe and heat plate (not needed when plate is grounded) ….

In this video we will find out how to do reflow soldering. We need to use this technique when we are dealing with supery tiny ICs which is the case for my new project. So I will be trying out 3 different reflow soldering methods: hot air, sand and a reflow oven. At the end we will find out which method worked out and I will tell you which one was my favourite. Let’s get started!

In this video I will show you a simple trick to solder SMD Components on PCB, using sand. This trick allows us to solder small to big any size PCB within a minute.

Comments:
It’s only applicable if all of your SMD components are at the top layer.

induction heating can make some sensitive component damage. better to switch off the induction heater before keeping the pcb for baking or use simple temperature controlled heater.
