WHAT IS PROTOTYPING? In electronics, prototyping means building an actual circuit to a theoretical design to verify that it works. An electronics designer often builds the first prototype from breadboard or stripboard or perfboard and usually uses them to test circuits. They are generally called prototyping boards.   Prototyping boards have holes to which you affix electronic components to bui...

Through-hole Assembly
2022-03-14 217
Through holes on a PCB refer to a hole that is drilled from the top and through to the bottom of a PCB, these can be plated (PTH) or non-plated (NPTH). Through-hole technology, also spelled “thru-hole”, refers to the mounting scheme used for electronic components that involves the use of leads on the components that are inserted into holes drilled in PCBs and soldered to pads on the opposite side...

BGA Assembly Capabilities
2022-03-14 180
BGAs (Ball Grid Arrays) are SMD components with connections on the bottom of the component. Each pin is provided with a solder ball. All connections are distributed in a uniform surface grid or matrix on the component. Common grids are nowadays: 1.27 mm - 1.00 mm - 0.80 mm - 0.50 mm. With several hundred component connections, the number of „routable" pins is limited per layer. The inner pins of t...

Mixed Assembly Advantages
2022-03-14 153
Though surface mount technology has become the main mounting method in PCB manufacturing, there are still some components that are not suitable in SMT assembly. Then SMT assembly and THT assembly need to be applied on the same board. This combination of assembly technologies is called a mixed assembly, which does not use solder paste during the manufacturing process. Most of the components are wel...
