hi all....
i just wanted to know what is the best material used to make pcb.... i mean should i use copper glad or copper plated board to make PCB...
Actually right now i am using copper glad to make PCB... but the problem is when i try to desolder it... the Copper gets peeled out from tge board.... or sometimes it even get peeled while it solder it...
i am using glass epoxy copper glad board.... is there any other boards which i can use to make PCBs or need to plate copper on any non conductive sheet...

- - - Updated - - -

initially i started making PCBs using toner tranfer method.... but again while heating the board for 10 minutes with hot iron created a problem... the copper gets peeled out due to access heat... so i started using UV process.... but again it it gets peeled while soldering.... are any other types of board availabale in market...
 

Copper clad FR4 is the standard.
 

Hello ,

i saw where the problem was from your description.
copper clad PCB is not the problem for copper peeling during soldering , the problem is that you soldered PCB too long time.
normally, the copper clad PCB can understand the soldering temperature 288 degree for 30s, you informed you solder PCB with iron about ten minutes , it is cause copper peeling for sure.
suggesitons:
1. you can choose Hi Tg PCB material which can make the boards with better heat resistance .
2. you can choose wave solder to replace iron solder manually.
3. you can lower the solder temperature of iron to make it close to 300 degree , but you should lower the soldering time if you want to avoid copper peel off .

i hope my words above can help you out .
 

Hello!

I'm not sure whether this can help you, but here is another point of view:

Instead of making PCBs yourself, you may consider having them made by a pro. Its' very cheap
these days, and there are tricks to make them even cheaper.

Advantages of a PCB made by a pro
- The PCB you get will be extremely good looking, and you can have silk print for no extra money
- The holes are metallized, so you can have decent good looking 2 sides PCB
- You can also make 4 layers very cheap (not even twice the price of 2 layers).
- You don't have to keep dirty chemical stuff at your home
- You can make very thin patterns (down to 0.125 mm in my case for the regular fee).

Tricks to get it even cheaper:
You can order PCBs by panels. One panel means that you arrange a certain number of PCBs
yourself inside of a rectangle and take care that there is no unused space or at least as little
unused space as possible.
You can therefore group, say, 5 circuits on the same panel. It will cost you some extra money,
about 10% or even less in my case, but you get 5 circuits.

In my case, I order about once a month, and since I'm not smart enough to make a valid circuit
at once, I always have fist trial version (alpha) of this one, corrected version (beta) of that one,
release version of that other one, etc...

I usually order 10 panels, which results in 10 x n circuits for a few 100 euros. Note that I'm using
a local maker in Japan, but I heard there are Chineese makers who make your circuits even
cheaper. I have never tried, but it's possible.

Last trick: if you have the possibility of working with other people (for example in a club), then
this would allow to order together and you would get professional grade circuits for an extremely
low cost.

Dora.
