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.

Can I use LEDs without PCB?

I recently purchased LEDs on ebay that were supposed to come attached to star PCB (as a heat sink). The items I received are just the LEDs (no PCB). They are listed as 3W LEDs, with a forward voltage of 3.0-3.4V, and current at 700mA.Will I damage/destroy the LEDs if I use them without a heat sink? Als niet, what is the best way to mount these to preserve their life during operation?

How do components not get knocked off or fall off during reflow?

Last week we visited a PCBA factory. We were looking at reflow ovens. A lot of them have a metal conveyor belt the boards sit on. On a double sided board, when you put the board on the metal belt, won’t the metal belt knock components off as they are only held on by paste?

Hoeveel speling moet u aanhouden in de gaten in de componenten die door de gaten gaan??

Is er een algemene regel over hoeveel speling u moet toevoegen aan componenten met doorlopende gaten?’ gaten zodat ze gemakkelijk passen? Bijvoorbeeld, if I have a component with 1mm pin diameter, what should the diameter of the holes for it’s pads be?
