هیت بد ( PCB Heated Bed ) پرینترهای سه بعدی دلتا

The PCB still has a side with the traces on and a side without but now the silkscreen is on both the top and bottom, this makes it look good even when 'upside-down' under a layer of glass. The LED, resistor, and power wires can be mounted on either side of the board, with either surface mount or through-hole components. If you are using through-hole be careful when soldering not to interfere with the glass and introduce a gap between the glass and the PCB. If the MK2 board is made properly without copper plating then be sure to only solder the LED and resistor to the same side and the tracks. This problem is solved in the MK2a by removing the pads on the non-connected side. This heat bed keeps the extruded melted plastic and prevents warping. The LEDs are optional, but if you choose to use the LEDs you MUST install the resistor.
