The main difference is that the volume of production for board-mounted AC-DC converters is very low, so you pay a boutique price.
Decent quality fully approved (safety and EMC) wall-wart adapters are made in huge volume so the costs are relatively low.

#PCB Assembly
We got a quotation sheet of four layers board but it greatly exceed our budget. So now we are thinking about reduce layers to save cost. Does this solution work?
Some online tutorials about soldering TH components, like transistors and ICs, are delicate components and can be easily damaged by heat. When it comes to soldering surface mount IC and components, some prefer to use a reflow oven which heats up the them to a temperature above the melting point of solder. So why?
To my understanding, each process in the operating system contains its own separate Process Control Block. Can someone explain this to me. Does each process have its own PCB or is there just one PCB that contains all the information for all the processes?
What Is PCB Assembly? PCB assembly refers to the process of assembling all electronic components such as resistors, transistors, diodes, etc. onto a printed circuit
When it comes to electronics manufacturing, the acronyms SMD and SMT are often used. On the surface, they look almost identical – just one letter
PCB assembly is not an easy job that must be handled with expertise and care to ensure your boards function as they are designed. Therefore,
