Is there a good source of buying large copper laminate? Or a good way to make it on my own?

I am making a large prototype of a device that requires a large PCB (about 15x20inches). I am able to etch my own circuit board in copper laminates, but I cannot find large enough laminates. I have checked Alibaba and aliexpress and they only have a few suppliers that make laminates that big.

Laminate is actually manufactured in large sheets on huge presses (at least 1m*2) similar to plywood and other sheet materials. If you’re seeing small panels, they’ve almost surely been cut up from larger sheets unless they’re some exotic material.

It’s not hard to buy medium-sized pieces of laminate, but getting a good price may not be easy, and shipping something that large will (especially internationally) will tend to be expensive.

You might have to contact a local PCB maker and ask them to sell you some or ask a wholesaler to cut down a big sheet so it can be shipped at a reasonable price.

How common is it to receive PCBs with failed or weak vias?

We had a number of flexi-rigid PCBs fabricated and assembled by a company in the UK. When the boards arrived and we tested them, we discovered a couple of failed vias, which we fixed with jumper wires. How common is it to receive PCBs with failed or weak vias?

How can I electrically isolate a PCB from a heat sink?

I have a set of LED driving lights for motorcycle that must be wired through a ground-leg pulse width modulation dimmer. The problem is the mounting bracket for the lights is grounded, so the lamp shorts to ground through the motorcycle chassis and the PWM dimmer cant dim the lamps. How do I handle this problem?

How can I separate PCB antenna and SMA connector?

I am designing a prototype PCB for a Lora node. It will have an SMA connector (J2) and a PCB antenna. Switching RF connectors are not available in my area, so as an amateur enthusiast what is a good way to separate the antennas?
