Re: laminator

2003-11-05 by dsv1486

Ok so it is strangely silent on this topic. So I will let you know 
what I am doing. I purchased a laminator from a place in Chicago 
called big lots. A store that buys discontinued things and sells for 
a reduced rate, I paid 29.95 US. The specs said that the maximum 
temperature is 100 degrees Celsius. So I tried the process on a 
copper clad board with zero results. Discouraged I left it and tried 
the iron method. I cannot get the results that many have experienced. 
The traces are fat and jagged, there are voids etcÂ…
So when the thread on the laminator unfolded I was prepared to buy 
one at Staples if someone had proven that it worked. As usual no one 
has just a lot of speculation research, which to me is useless unless 
results can be verified. So I proceeded to take the laminator apart, 
which I had purchased. It has bimetal thermostat connected to a one 
shot that tells you when it has reached operating temp. I placed a 
switch to short out the thermostat and let it warm up 10 minutes and 
tried a board with glossy paper (national geographic in case anyone 
wants to try the same and it is easy to get). I ran it though about 6 
times and placed it under water for about 5 minutes. I was surprised 
to see clear results however there were some parts that did not fuse 
to the copper so I determined that I need more heat. I placed the 
cover and let it warm up 20 minutes and found that the nylon gears 
melted on the rollers. So now I have to cast new gears and try again. 
So my question to ones that have successful laminators, what is the 
temperature that they operate at so that I can replicate the 
results????
