Xover PCB trace width and design recommendations

[01-0077]

I use EasyEDA to design my boards for the fact that it is free and it creates Gerber files which are then uploaded to jlcpcb for the order process. JLCPCB can produce through hole and smt boards and even supply and solder smt components to the boards for you. Here is an example of an smt board I had made, these boards measure 74mm x 49mm ~ 3" x 2" and the components are tiny. I got sick of toner transfer and etching my own pcb's and find the price, quality and turnaround time of the jlcpcb boards to be excellent.
