PCB Laminator on the Cheap

hello guys

who tried to transfer toner ink to pcb by iron?

every time we do this we fail maybe 4 times before operation success

and for better results you maybe need to buy PCB laminator , it's good machine to transfer toners ink with much heat much pressure .

BUT!!!

you don't have to pay 150$ to buy new one designed for PCB's

you just have to modify cheaper card laminator to get same results for less than 30$

lets see how in few steps

Step 1: Parts and tools

in my case

i bought cheap card laminator and when i opened it i found 2 thermal switches . so we need

  • 2 pieces of thermal switch 170 Celsius or 175 normal close
  • screw driver
  • card laminator (or you can decide which size you need)
  • some handy skills :)
  • mini engraver rotary tool or file tool

    Step 2: Let's explore what we have

    Now check your machine is unplugged

    and unscrew all the screws :)

    find the thermal switches inside like first picture

    take off the wires of it and unscrew them from the laminator

    when i take them off my laminator i found the first one is 105c and the second one was 145c

    now install your new thermal switches . and go the next step

    Step 3: Checking every thing is ok

    in machines have a heater they add thermal fuse for safety to avoid damaging heaters

    so we have to check temperature rate to make sure everything will be OK

    in my machine i found thermal fuse is 192c so i don't have to worry about it .

    actually thermal switches will stop the heater at 172c so it will be fine to leave this fuse

    but if you have fuse lower than the thermal switches it will burn before heaters reaches the maximum heat

    so make sure to short it if temperature rate less than 185

    Step 4: Results

    Now i tried to transfer toner from glossy paper

    and it worked better than manually ironing the paper on the PCB

    you can see the thinnest tracks printed well with no mistakes

    have fun :)

    Step 5: Increase thickness between rollers

    Now We need to make feeder accept PCB thickness

    so first look at rollers

    find this one engaged directly to the motor gear and leave it

    the other one we need to loose it more to fit PCB so we have to increase diameter of shaft holder by 1mm from the side beyond of the motor. using mini engraver or small file tool

    reassemble the parts togther again and make sure the shaft can move 1mm up and down

    now you can try to put PCB inside with no worry of stuck inside
