check out www.lavenir.com for a free Gerber viewer. they also have a 516 page pdf file which has all the d-code conversions etc

Hello, I'm a beginner in the world of making PCBs. I seek for a website which offers cheap Ferric Chloride and a Etch resist pen (that's all I need, right?) Best Regards, Aviv Revach

They are in the "Drafting" section of STAPLES, not in the "Pens" section. There is a little kit of 4 with different widths for a couple bucks.

I had been unable to find the specific Staedtler #318 Lumocolor locally. But I see Office Depot carries a Staedtler Lumocolor pen meant for marking directly onto non-coated CDs. Which means ultrasmooth, which means they should work on copper. Listed as waterproof and permanent. I'm going to pick one up and try it. I'll let you know how it works.

Although it is nice to get an honest opinion of EasyPC, I don't want this to turn into a group for ads. What does everyone think? Ban ads? Ads allowed only on one day a month, like some other lists? Free-for-all? A quote from the auction: "I'm hoping I'm not the only idiot in the world for buying this trash! I don't know, may be you think Easy-PC is the best thing since sliced bread, in which case you now have the opportunity to waste your money and help me recover some of my loss. The Easy-PC program sucks. ! I want rid of it."

I want to get a plotter what would be the right one I now have a calcomp 1034 and it can not be used for this type of work . What would be the best one to get.Thank you group I have seen a lot up for bid on E-bay

seems to be a broken or non-existent link.

Hi, Just found some pcb cad that works in linux: http://www.illuminated.com.au/home.html

Hello, Has anyone come across drivers to print form EasyTrax? Or is there a way to get the file into Windows to print it? Thanks, Brian Gracia

How thick can you make a PCB ? I want to use one for mechanical strength as well as electrical wiring. Jim Ubersetzig

This was bounced back so I am posting it here. Sean I actually purchased my tank at Circuit Specialists. Here is the spec sheet on it. http://www.web-tronics.com/lowcosetsysw.html As you can see it uses a standard fish tank heater and pump. The air is pumped into the side at the top and it travels down the side to small holes in the bottom its that simple. You just want gentle agitation of the ferric chloride. Pick up the FeCl at any radio shack. The heater need to be set till the tank is warm to the touch. It takes only about 3-5 mins to etch the board. Use gloves and other safety equipment. Hope this helps Derek

Hi, I have been lurking on this list for ages, as I want to learn more about electronics (especially interfacing pic chips to the real world), but as of yet I am still learning and mostly confused! :o) Although I can assemble small project PCBs and roughly understand how they work, my understanding of why "that" resistor is "there" is next to zero. I have a couple of questions for the group. 1. are there any good basic electronic foundation tutorials on the net? all the ones I find are too basic (like what a resistor is) 2. Anyone here have any experience of ultrasonic cleaning baths? I have the schematic for the electrical side, with an explanation of many of the components, but I have no idea what specific components to use, anyone interested in looking at the schematic, helping me make one of these and furthering my electrical experience and understanding? thanks in advance Jon PS: Anyone here ever known someone to buy one of the cheap (under $300) fibrescopes? (also known as a borescope or endoscope)... I would love one of these, but I suspect they are trash.

This link has a good description using conductive ink to actiavte the holes and then plate on that. http://www.thinktink.com/stack/volumes/volvi/pcbproto.htm I'm using eyelets. Recently I got some eyelet samples form Mill-Max 0.037 OD and 0.024 ID Any know of and smaller eyelets ?

I was wondering if anyone had a better way of "printing" PCB outlines for reproduction. I use Ultiboard as my design, routing program. It allows saving the document to Adobe through Distiller. When I open the document (in Acrobat) and magnify it, however, it looks as if the doc has been saved as a somewhat rough bit-mapped file. If I just print the diagram to my laserjet, everything looks great. For now, I have been fixing up the jaggies in a drawing program. Time consuming. Anyone have a better way -- scanning in hi-res produces too big a file btw.

Hi all, To make spray-on prp resist work well, the copper has to be cleaned well. Some things that work: salt and vinegar, salt and lemon juice, citric acid, and probably lots of others. I like citric acid the best, as its ok to use in the kitchen. Mix up 30-50% powdered citric acid (sold in supermarkets), with hot water until disolved. Wiping it over the pcb blank with paper towel is sufficient to degrease it, without any harsh scrubbing needed.
