Miniware MHP50 Mini Hot Plate Preheater

Miniware MHP50 Hot Plate Preheater, a pocket-sized tool for de-soldering, reworking and repairing PCB’s.

This Miniware MHP50-B5 Hot Plate Preheater is the new and improved version of the MHP30 Mini Hot Plate Preheater. Now with a larger heating surface 50x50mm, bigger OLED screen, DC5525 and USB Type C power input jacks, built in fan, and reduced overall height which makes the platform more stable.

If you’ve ever encountered the intricate task of mounting SMD components, or even trickier, the delicate process of removing components from PCBs, you’ll know that it can be quite a challenge, if not impossible using a soldering iron. That’s where a hot plate such as the MHP50 comes in handy. Armed with the MHP50 and some solder paste, tackling SMD components becomes a breeze. Removing components too, with a bit of luck also becomes easier. It’s simply a case of heating up the PCB and then using tweezer to lift the components away from the board.

MHP50 allows users to set an appropriate operating temperature, ranging from 100°C-350°C. It heats up quickly, around 150 seconds from from 30°C to 350°C.

This version of the MHP50 comes with a heating plate made from brass (MHP50-B5). A built-in high-speed fan ensures accurate and even heat dissipation. Benefiting from a nano-ceramic coating, the heating plate is easy to clean. Once cool, any hardened solder left on the hot plate can be brushed away.

Sharing many of the innovative functions that came before in the MHP30, the MHP50 Hot Plate includes smart features to setup and customise your heating parameters. A clever heating curve function also allows you to customise the heating temperature and duration by sections, achieving a reflow soldering effect. It also has a LED light which changes colour based on the temperature of the hot plate, effectively telling you when the hot plate is safe to touch. In addition, the MHP50 Hot Plate features a full colour LED display and intuitive interface.

To power the MHP50 you have two options. Either supply DC 19-24V via the DC 5.5×2.5mm barrel jack (supports 150W), or use a USB-C PD power supply (supports 100W), common these days as laptop power supplies. Please note the two power supply ports can not be used at the same time.

Overall, the Miniware Hot Plate Preheater is a great all-round tool for PCB work, whether assembling brand new circuit boards, doing repairs or reflow work.

Features:

• Adjustable heating temperature range from 100℃ to 350℃.
• Intelligent temperature control algorithm, supports temperature compensation & power adjustment.
• Power Input: Supports USB-C PD, DC Max 24V.
• OLED display
• Supports ℃/℉

Please be careful when using this device. Treat a Hot Plate as though it was an open flame. Do not leave unattended.

The basic process for soldering a PCB that has SMT parts (source https://reprap.org/wiki/HotplateReflowTechnique – more info here):

• 1. Apply Solder Paste to all the SMT pads.
• 2. Place all SMT components in the appropriate place.
• 3. Heat up the entire board to melt the solder and solder all parts simultaneously.
• 4. After the board has cooled, fix any solder bridges.
• 5. Solder in the remaining through-hole parts, if any.
