Using Cool-Amp does require a bit more work though. I also sometimes use MG chemical's "Liquid Tin" that comes in a pre-mixed and ready to use bottle, but I like the results a bit less than what I get with Cool-Amp powder. Nice boards, have you tinned the copper with something if so what do you use?Įven just a 2 ounce bottle would last you a very long time. pick only a few, like maybe 45 and 90 for all traces.ĬARL: I'm assuming you are trying to use a laser printer toner transfer method. that way, everything is on the same side. It might be easier to just use ALL through hole parts. but since you are using many through hole parts already. Using surface mount parts is usually done to save space. It can be a rewarding experience if you let it become one. so you want to design your board so that IF you need TOP SIDE traces, they are all the shortest possible straight lines you can run as "jumper wires".ĭesigning PCB's is sort of like solving a complex puzzle. you can't really do double sided PCB's at home without at least getting better experience at single sided. so farming it out does not seem to be in the plans.Īs others have said.
They said they were going to buy some ferric chloride.I don't run around telling people "Don't eat cabbage because it sucks and smells funny." I allow people to figure things like that out on their own.There are probably much better examples of of good places to get PCB's made. PCBexpress is a sort of good with the bad experience due to proprietary tools.Making a PCB at home is not fun, for you.With a little patience and experience you can make perfectly good boards at home. It is my opinion that not everyone needs to take your advice and give up making their own PCB before they even try. DVDdoug, your experiences are very personal.
