Hello All:
'
I'm looking for a heater.
'
The heater needs to heat a 6"x6"x.0625 area evenly.(A PC Board)
'
I need 250F to 350F temp range from the heater for about 5 to 15 minutes.
'
I'm not really sure what this heater would be called? So My searches have not produce much info. I have seen these heaters, But I can't remember where?
'
Below is a quick sketch of what I'm after.
'
Thanks in Advance for any help or ideas.

How about using a heat film?

Hmmm.... for some reason the exact link is not working. Try looking at their product number 35475K632, for example.

How many watts does it need to crank out?

Oh, if money were not an object. Or can you say lottery or huge development contract or grant........

T (http://www.zeph.com/systems.htm)ry this one as a starter. You may be able to clone something like this. otherwise check sparkfun for an equivalent knock-off.

6" x 6" - 450F, $161 - Need to make your own controller.

This is offered as an idea needing more research BUT: I spoke with a fella yesterday, we was building a "Hot plate welding station". It's all automated, PLC etc, etc but the whole thing hinged on an electrically heated plate to heat two fairly large pieces of plastic to 400F then press them together


Also, I read Jameco's story. He started building boards in his apartment with a $40 electric skillet from Kmart.

How about a coil hot plate that you pick up from KMart and attach a machined aluminum plate to the top of it?

Just to repeat myself: It's important to know how many watts you might need. Just because something can withstand a certain temperature, does not mean it can necessarily crank out the wattage your application will require. So you should try to get some ballpark number on how many watts you need.

If you're making a PC board from scratch, any chance you could design the heater into the PCB unit itself?
I don't know what I'm talking about, but I've seen "cupcake" heaters made on PCBs for Makerbots which can supposedly go up to 212 F "easily".

Many thanks.This is just what I was looking for.
'
Two 3" wide strip-heaters on a machined aluminum plate should heat up nicely.
'
I already figured I would have to make my own Temp. controller.
'
I have a few DS2760 T/C readers for this.Along with a BS2...Pretty simple project.
'
Thanks again.
'
P.S.--Why couldn't google find this?

Keep in mind that McMaster sometimes charges 30% to 100% more than what you might pay if you shopped around some. But the good thing is that they have almost everything in their catalog in stock, makes for great one-stop shopping, and it ships very fast. If you like the item and it works well in your prototype or whatever, you can often hunt down who made it and find a cheaper source, especially if you want to buy them in any quantity.

Happy heating.
