I was reading about ways to print your own PCBs, and read a few forum entries here as well, and - besides sending off to have it printed/made for you - the simplest seems to be using copper clad board and etch resist ink pens. The tracks in the photos I came across on other webs seemed quite wide, ...and "a bit cludgy" would
I had some success with copper plating this weekend. I got an used matrix board and painted the reverse side with a graphite paint I made. I mixed White nite kill rust clear with some lubricating graphite to a creamy texture and then painted the fibreglass surface. I gave it a very rough sand and then electroplated in copper suulfate solution wi
You can use 3/8 oz. Cu on RO Dk for outer layers, 0.5 oz for Epoxy clad layers and 1 oz layers for Vcc and ground for strength on uneven etched signal layers to prevent warp. Also 1oz gives lower conduction losses, and lower crosstalk with appropriate prepreg in between also. As well better tolerance on 3/8 Oz fine line copper over RO Dk. (ROger
Who knows where to get small quantity (100...400 m) of 0.5....0.8 mm CCS wire with 19...40% IACS conductivity? Shipping location will be Europe, Netherlands.
For mechanical stability I would like to use copper clad Steel wire instead of solid copper conductor. I already tried 0.6 mm copper coated MIG welding wire. However the copper coating thickness seems well below 5 um as at 150 MHz a got extremely high resistive loss compared to solid (...)
The thickness that is specified is typically the thickness of the dielectric substrate, and does not include the outer copper clad thickness. So a 200um controlled thickness board with 35um (0.5oz) copper will be 270um thick overall. (Cross section = 35-200-35)
I need to construct a circuit that takes in 3-3.7V, 2amps and outputs 5V, 1amp....instead of going through the stress of the common local etching, drilling and the rest of a copper clad...I would prefer to consult companies who takes in your design, comes up with possible circuits and design the module in line with your specifcations e.g length of
Hello, Is the only purpose of prepreg to act as a cheap separator for the copper layers of a PCB? Is it true that we would ONLY use prepreg (and no core material) if the prepreg was a bit more sturdy and rigid? So can we conclude that in any given PCB, no matter how many layers.....only ONE layer of rigid FR4 core is ever needed.? ....a
I have been having good results with a new toner transfer technique. Put a heavy hotplate on the stove and dial in a temperature of 175 °C using a thermocouple. Bond the toner image to the copper clad board by placing them print side down onto the hotplate between two sheets of paper and applying pressure with a rolling pin for 2-5 minutes. For dou
Your cost targets are too low. Best Proto shop from my experience that can do anything you ask them to. Ask about thin Getek for RF over 2oz copper cost comparison with MCPCB. They offer no-touch discounts, Web order discounts and premiums for 24hr turn around. Ask about micro-via costs for RF and thermal transfer. https://www.protoexpress.c

I like the homebrew way and the flexibility of both techniques. Manhattan: copper clad,PCB,metal shear,metal nibbler,metal punch,soldering iron,super glue Dead bug: But the problem with Manhattan style is these little pads that separate
i am confused with laser powers , i want to make a cnc pcb machine as a final project . any body having a work experience on LASER's ? what power is enough (no more no less) which can etch , drill , and cut a (copper clad) pcb board . i just want to use a single laser module . would i use 10w-20w CO2 or less power would be suf
i don't thin it will work, there is cd holder for printing cd's , if using copper clad you have to fix it the surface with some method, but the risk is touching the printer head...
Folks, I'm making a write-up for a workshop. The class is on PCB layout, but I want to give students an idea about PCB fabrication too. Is this a the correct step for fabrication with photolithography? 1. copper clad FR4 substrate – starting point 2. Drill 3. Plate 4. Apply photoresist 5. Expose photoresist 6. Wash off unexposed
The copper is milled from the fibreglass material using small high-speed grinding tools. The isolation areas have no copper! I have this facility but still prefer chemical etching :).

Hi, can anyone let me know the minimum width of trace for a presensitized copper clad board (Pcb that processed with a UV light)? I have trace of 0.4mm in width(this width is due to the leg of component ADS7861, i cant make it wider or it will overlap). Can i make my design in that UV Pcb? Will the trace be disconnected for when i fabricate / etch

ANSI/EIA 274-D is the standard for G codes used for numerical machine control. It is sometimes called RS-274D format. It translates a drawing into a series of ASCII G codes to move a machine for manufacturing. In electronics it is used to control photoplotters for manufacturing masks to be used for exposing photo sensitive copper clad boards to

Hi, Can anybody help me to find address of compaines suppling copper clad Boards, Photoresist and chemicals in India regards Raju
No need for simulation. Just take a piece of copper clad PCB, drill a hole for an SMA, and solder the flange to the ground plane. Then solder wire to center conductor and trim until return loss is good. You can also use wire as a counterpoise instead of PCB.
The thickness of copper clad on a circuit board is usually given in ounces (oz). It is the weight of copper on one square foot of board. One ounce copper is 1.378mils (~35um) thick. Normal PCB copper thicknesses are 1/4oz, 1/2oz, 1oz, and 2oz. Other thicknesses are possible, depending on the (...)

hi first of all translate ur design to ur copper clad board by using photo sensitive matarials .then etch it in a ferric cloride solution ,keep it shaking for a while so that copper get etched off , then finaly clean it with ethonal solution. nikhil
I've used a angle grinder, but it's too rough.
A PCB pen can be used for simple layouts, layouts you can draw directly on to the copper clad board at one sitting. Then you drop it into a tray of etchant (ferric chloride solution) and the copper not covered by the ink gets etched away. The board has to be extremely clean, otherwise the tracks get smudged and / or etched.
Seeds are what things grow from, flowers, trees, copper clad boards. If you give your board a seed then your copper can grow from out of it. Its like a starting point, from which the copper can grow all over the board. :)
Depends on copper thickness, width, how hot you want it to get... Take a look here, a trace-width calculator... or here, for a simpler one... Cheers, FoxyRick.
Hi friends Did anyone knows how to use photoengraving glue for exposing copper clad. I think that has to mix with water and Ammonium bichromate. if anyone knows how to prepare the photosensitive solution please share. I hope the procedure for making blocks for printing press is same. regards Benoy
