Laminator recommendation needed for PCB transfer method.
castingflame:
I am in need of a laminator to replace my Peak to create homemade PCBs using the transfer method. The Peak 332 keeps tripping the circuit breaker when the heater is turned on. I can not find a schematic for it. Nothing seemed dead short on the heater side but I really had little idea what to look for.
A3 would be great but A4 will also be considered. I dont have a fortune to spend so £100 would be the max.
I use the shiny yellow PCB transfer paper you see on eBay and AliExpress. I am unsure what the temperature will need to be so advice on this is welcome.
Thanks in advance for any help.

I used to use a laminator for dry film solder mask. It's GBC H220 which I remember getting because it takes PCBs ok and you could swap some gears to speed it up.
I hardly used it and don't use it now, so if you can't find an A3 one, make me an offer.

I abandoned the toner transfer method for a far more accurate dry film method but I still use the same laminator as before .A Fellows Saturn 3i 125 because it was cheap.
With a few modifications (trimming some of the plastic ) to allow thicker PCB to be passed though. At full power it still takes 3 passes to properly adhere the dry film.Needs around 200 degrees C to adhere.For double sided PCBs laminate both sides prior to exposure.and I use guide pins through the PCB at the corners of the negatives to accurately line up the front and back artwork. 5 minutes of UV exposure for each side works for me.The process takes a little longer but well worth it for the better resolution traces.

I use the Tahsin SM-330. I do not recall the process details of determining that this is the RIGHT one to use but I did a lot of research. It has performed well for me.
I made a PCB yesterday, in fact. Some say "blah blah blah" about doing your own PCB. Fine, I send out for PCBs as well. There is a certain satisfaction derived from doing one at home. I was confronted with a problem to solve this week...where I had an application note with a single-sided PCB image given in the note. I needed to build the circuit to meet my client's request. So, homebrew PCB was the perfect solution.
I do not make them often, but if I need something really quick and it is simple...then homebrew is always in my back pocket.

I also use thinner pcb material to run through this machine...28mil (~0.71 mm)...I dont know what the official spec for the thickness is...this is what I measure. Easier on the rollers.
a-nudder edit
I use the shiny yellow stuff too. I print with an HP P1102 printer.

First swap out the MCB for a known good one as they do degrade over time after some trips.
If it's an RCD type MCB then you should check for some earth leakage issue.
I use a Rexel laminator, 2 passes with the PCB and transfer in the Rexel carrier sleeve. No mods required.
