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, 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

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 (...)
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. :)
I've used a angle grinder, but it's too rough.
i want to cut down the copper clad into box shape very precisely,so can u tell me any method or any tool used for that!
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 :).

you have forgotten too add a choke stub to the power rail my pal you also need a choke stub on the audio rail vc control rail these are crytical componets dont rely on just capacitors or resistors to decouple the supply rail and i think this circuit will self oscillate unless you use ceramic pcb {copper clad c
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
To reduce the noise for the mixed circuits some attentions should be paid.. - Very good seperated ground connections that are converged onto only one point which is power supply ground.. - Very clean noisless power supply - Seperate VCC lines which are passed "feedthru" capacitors into concerned circuits - On the VCC lines , some inductive lo
Mona, I have a different question: can you print on copper clad board ? I am thinking if this printer can be used for home made PCBs. JJ
I made the upgrade board according to the PicStart_upg.pdf and connected pin 19 of the 18F6720 to +5v which the schematic did not show. I programmed the board using the Picstart + and it worked fine. I tried the programmer with the upgrade board, updated the os throgh MPLAB update, erased, read and programmed 16F682A, 16F84, 17C44, a 16F871 and eve
i should reiterate and note that whether the material is foam or not is not as relevant as price and dK i have found an Arlon product Foamclad which is a copper clad foam with a dK of approx 1.35 at 40 mils (no plated thru holes in processing however) this material is around 50 US dollars for an order under 1000 square feet in sheet (...)
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.
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
Hi I am newbie in the microwave stuffs and I want to improve my skill on this.I don't have many things in my homelab ,so that I need to know how can I design electronic circuits using Microstrip for microwave purposes .also, is the microstrip layout board like the ordinary copper clad double-layered or what .Which PCB I must buy to implement th
Hi, everyone. I have a question about the conventional PCB trace thickness. What is the relationship between the thickness and copper weight, since I saw many PCB manufacture give the specification of copper weight. Thanks.
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.
I am assuming that you'll get your screen done elsewhere. You can do it yourself but its not easy to reach good yield. Anyways, after you get your circuit in a screen form, you basically paint a clean copper clad/laminate. After a while, you'll etch the board and then drill the holes. Later the paint can be removed with any off-the-shelft paint rem
hi all i need information or any kind of help in my country no exposure printed board only Printed Circuit Boards - Standard copper clad and i can get chemicals Potassium Dichromate my problem how to use chemicals Potassium Dichromate on the pcb to make it exposure printed board any information or link or book please thanks in advance
hi there i have made a pcb and i take it on on "A4 SIZE PAPER" so what is the way of transfeering these trace on copper clad board without ..peel n press paer...and without photo glossy paper.... please reply
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, I had designed my own Home made PCB Layout and successfully got in the copper clad..But i dont have idea about how to apply solder Mask in that PCB.. Can any one Help?
wow karesz, you are a most generous and kind fellow. Has me thinking I could send you my next schematic and you produce PCB for me, I need do nothing:D Anyway, don't you think the OP is probably a 12year old kid ? in which case I wonder if he/she has learn't anything ? It would have been better to steer the OP at vero or matrix board to le
for single side pcb's screen printing is ok you can print directly to copper clad from printer ( search internet for altered printers), but i don't think it can be used for production you can remove photoresist in sodium hydroxide solution the tinning is done after the solder mask coating, the simple method is screen printing the solder-m
I am from India and i brought the tube from polymer stamp making dealer, you can get it in electrical shops, I tried first with 40w choke but I was not able to find the starter for that (not working) so now I am using it with 4 20w choke, what type of copper clad you are using ie photo resist or pre-coated one
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
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...

Can I use a 1 m long waveguide at 200 MHz, if it is filled with distilled water (then the wavelength will be about 18 cm), and made from copper-clad PCB laminate with the Cu layer on the outside? Won't I have problems with total internal reflection at the water/PCB dielectric interface?
