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 is the Aluminum Clad PCB panel panel separated after assembly?

This might sound trivial, but I only have experience with standard PCBs. I need to design LED tube PCB and is only 20mm wide, so there will be at least 10 pieces next to each other on one panel. How to design Aluminum Clad PCB panel – how is the panel separated after assembly

Why did the SMT pad fall off easily when soldering the PCB boards?

I am a buyer in a telecom company. Recently, an important order of SMT PCBA is delayed due to insophiscated production of a supplier. I am thinking about replace it and just very puzzled about how did their SMT pad fall off easily when soldering the PCB boards. That slows down the whole process.
