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
I’d like to use a processor that uses a pin grid array. Basically, I’d like to make the prototyping PCB board for it. I’m new to eagle. How can I connect the inner PGA pins to the header pins on the edge (without shorting the lines)?
In my current prototype, I have a SIMCOM GSM module and the gp-635t GPS. They are both in an enclsoure including antennas (gps antenna is integrated). What I experience is sometimes poor GSM and GPS connectivity and sometimes GPS doesn’t get any fix (in the 2 minutes of time i allocate for it) and the GSM fails to send data sometimes. Any tips on this case?
On a Flex Printed Circuit (FPC) made out of Kapton polyimide, will anything bad happen if I put a VIA in a part of the FPC that has to bend? VIA size: 0.2 mm hole diameter in 0.4 mm copper diameter. FPC bend radius: 0.7 mm. Kapton thickness: 0.2 mm. Copper weight: either 2 oz or 1 oz (I haven’t decided yet)
What Is Prototype PCB Assembly? Prototype PCB assembly refers to the experimental phase that follows the PCB design to demonstrate the feasibility of the design
In the manufacturing process of PCBA, soldering is a very important process, which is used to achieve the electrical connection between all components and the printed
When it comes to electronics manufacturing, the acronyms SMD and SMT are often used. On the surface, they look almost identical – just one letter
