Need More Heat - GBC Laminator (pics included)

Need More Heat - GBC Laminator (pics included)

2012-11-10 by dubob4432

Hello,

I need to get a bit more heat out of this GBC Creative Laminator.  Very close but probably another 10-20C would be what I need (ability to adjust would be EXCELLENT). How do I go about accomplishing my goal.  Has the Daewoo KSD602 thermostat - http://www.daewood.com.hk/en/productdetail.asp?id=122&sortid=210&pid=.

Any assistance would be greatly appreciated.  I did not remove the power board area but have no problems going into that area - I am so close, I just feel the toner is not being 'baked' onto the copper clad quite enough to stand up to the time in the muriatic acid / H2O2 w/ the bubbler and small, important pieces are coming off.  Doing .5mm pitch smd work.

Thanks in advance,
Bob

The easiest way would probably be just to replace the thermostat with a higher temperature one, like the process here:

http://ultrakeet.com.au/write-ups/fritzHack 
and here:
http://ultrakeet.com.au/write-ups/superFuserV2

Or if you wanted an adjustable controller, something like these:

http://kmprojects.wordpress.com/2011/01/29/pic-lam/
or 
http://screwdecaf.cx/yatc.html
or
http://www.delorie.com/electronics/laminator/

or just search Google for "open source temperature controller" or such.

Insulating the snap switch (temperature switch) from the aluminum heater bars will raise the temperature. On mine the snap switch is held on by a screw, put a piece of bare circuit board or cardboard on each side of the tab on the switch. Experiment with thickness till you get good results.

I've been using a thermal press with direct temperature read out on the aluminum heat plate. I can set temperature and pressure on the thermal press. 

HP toner will melt around 110C. might be even lower around 105C or so. At lower temperature, the toner may have a harder time fusing onto the copper.

Copper needs to be ultra clean. I use 0000 steel wool. followed by scrubbing with TSP solution using scotch brite (green) pad, then rinse with water then cleaned with isopropyl alcohol. Wear glove through out the process. Laminate image immediately to reduce contaminating the copper surface and oxidation. Someone thought oxidizing in the etcher for few second made the image adhere better. Haven't tried so have no comment about oxidizing surface.

I really do need reliable repeatability down to 6/6 mil. I may go to photoresist. Found a source at around $3.00/ft^2. Not cheap but claims to get images down to 1/1 mil. Stuff is called puretch. Distributor is an artist out of South Carolina. Think and Tinker has similar material not as high performance at around ??$2.00?? per square feet but you need to spend over $100.00 for the minimum quantity.

Result I'm getting out of photopaper of all different kinds, specially formulated toner transfer paper is just not cutting it for me.

Anyway, temperature set it around 105C to about 130C. At 115C and above the plastic coating on the photopaper will decompose and will turn into hard white film.

There is photoresist available on ebay.  DuPont Riston costs $2.20 per
square foot for example (item number 170919606000).  An average board size
for me is 6"x3" double sided which is $0.50 in photoresist.

 

On the topic of etching, has anyone used electroetching?  Does it compare
with ferric chloride or muriatic acid?

Perhaps a little fiberglass insulation between the sensor & heat source?

Maybe I am using too much heat - I prep as you recommend and once done, I put the piece in water and let the paper come off.  Once it dries, the traces are black but slowly turn white as if paper is adhered to the paper.

Possibly I am going the wrong way?  Maybe just 1-2 passes through the laminator and not 10?

Thoughts?

Mine do that also, after I remove the paper when it is done soaking. I rub my fingers over the traces underneath running water just to get rid of the paper residue. Your tracks should stay on the board as it takes a lot to remove the toner.

The trick to toner transfer is to get all the toner hot enough to become
"sticky" but not hot enough to actually melt.  There's a small range of
temperatures for each specific toner; the closer you can get to (and
hold) this temperature, the better.

I did a few experiments with transparencies...

	http://www.delorie.com/pcb/transparencies/

The copper needs to be clean enough to let the toner stick *and* needs
to be "roughed up" with an appropriate grit sandpaper so the toner can
get a mechanical bond with the copper.

Interesting post Mr. Cat.  Some people say don't use steel wool, as
traces of iron will stay embedded in the pores of the copper.  That
can lead to corrosion due to galvanic action.  However those dark
green 3M pot scourers work really well :-)

I get the white residue when using magazine paper. You won't get it if you use proper transfer paper.

It doesn't make a difference to the board, just looks weird.

What is the thickness of the copper clad boards of this project talk as I have been studying a different GBC Laminator of pulsar pro product number. I need info due to this Lamanitor found on E-Bay is about 1/2 price or less. Thanks Kevin

Maybe I will remove the paper like you describe and then heat up the toner w/ hot air?

Re: Need More Heat - GBC Laminator (pics included)

TSP (Trisodium phosphate) can be had at Home Depot, Lowes or any paint shop. It is a very strong degreaser with good wetting characteristics. only need about teaspoon to about a tablespoon per quart of water. Quart is about a litre off hand. I'll weigh out TSP in grams later and will advise. It is also alkaline so it doesn't corrode the copper.

The thin white film left over after cleaning is a very thin plastic layer with lower MP than the clear film on the photopaper you are removing. Photopaper has a very thin plastic layer at the top. Underneath is a thicker clear plastic layer with higher MP. Underneath is the paper backing. Backside has another layer of opaque matt plastic layer. There may be more to it but this is what I found out so far.

from top to bottom:
very thin plastic with low MP  (top layer)
thick clear plastic with higher MP
paper
matt white plastic with even higher MP (bottom layer or backside)

Found TSP on E-Bay, add for Lowes  and add for technical grade thru E-Bay. Have letter scale and could use exact weight in grams if possible. I have .94mm or .034inch board stock. What is the size of GPC Creative board stock. 
Max thickness? Thanks Kevin.

Stuff is called puretch. Distributor is an artist out of South Carolina. Think and Tinker has similar material not as high performance at around ??$2.00?? per square feet but you need to spend over $100.00 for the minimum quantity.

How do I go about accomplishing my goal.  Has the Daewoo KSD602 thermostat - http://www.daewood.com.hk/en/productdetail.asp?id=122&sortid=210&pid=.

I did not remove the power board area but have no problems going into that area - I am so close, I just feel the toner is not being 'baked' onto the copper clad quite enough to stand up to the time in the muriatic acid / H2O2 w/ the bubbler and small, important pieces are coming off.  Doing .5mm pitch smd work.

I always thought the copper needed to be super clean, but now I just use Scotch-Brite to give the surface a little tooth and CitraSolv concentrate. CitraSolv is a cleaner, but it is also a solvent for toner (and flux residue). Just go over the copper surface in different directions with the Scotch-Brite and then clean the residue off with CitraSolv (concentrate) until the wipe-off is clear. I usually give the surface a final wipe and let it evaporate. The CitraSolv residue acts as an adhesion promoter for the toner.

You need the copper to be super *oil free* - i.e. keep your grubby
fingerprints off it!  You normally don't need to make the copper shiny
or remove the oxides (in a CuCl bath, the oxides etch faster than copper
anyway).  Shiny is actually bad if you're using transparencies, where
mechanical grip on the copper is key to keeping the toner there.
