Why do people use multiple layers PCB? What are they required for?

We seldom use multiple layers in our product ranges, which cover all types of smoke alarm. What are they required for? Any advantages?

Simplify PCB Traces

Multiple layers make it easy for the PCB traces to route by jumping over from one layer to another to complete the path. Hence many complex circuits can be routed easily.

Compact

Also the demand for compact electronic devices boosts the need for multiple layers PCB.

Isolate Supply and Ground

In PCBs with 4 of meer lagen, supply and ground is separated. This offers isolation between supply and ground pins and hence avoids short circuit.

Hoe kan ik diodes en LED's op PCB's markeren om verwarring met Chinese PCB-fabrieken te voorkomen?

(Van ieder bord dienen wij een ontwerp in voor montage, sommige ontwerpers kunnen PCB-fabrikanten in verwarring brengen over de oriëntatie van diodes of LED's. En we hadden zowel de standaarddiodes van Eagle als de standaarddiodes van KiCad teruggestuurd door de Chinese fabriek.)

What does “run a panel” bedoel in de context van PCB/PCBA-fabricage?

A design engineer told me our PCB prototypes would be completed soon and then he would have his assembler “run a panel”. Does anyone know what that means?

What kinds of test is suitable for low volume PCB order?

I’ve ordered fabrication and assembly of small PCB batches (100st) a couple of times already. Each time the factory asked me if I want to do test on the PCB. But I don’t what to do about it. And I test them by myself. Vervolgens, the result of the testing is unacceptable with 15% soldering problems. So bad. I think I will ask the supplier to test them before delivery.
