DIP SMT PCB Assembly Service 4 Layer Prototype PCB Fabrication FR4 Circuit Board
The difference between SMT and DIP
SMT is usually installed on the surface of components without pins
or short leads. It needs to first print solder paste on the circuit
board, and then mount it through the patch machine, and then fix
the device by reflow welding. Dip welding is a type of in-line
package that is fixed by wave soldering or hand welding.
DIP Package (Dualln-ine Package), also known as dual-in-line
package technology, refers to the use of dual-in-line package of
integrated circuit chips, the vast majority of small and
medium-sized integrated circuits are in this form of packaging, the
number of pins generally does not exceed 100DIP package CPU chip
has two rows of pins, It needs to be plugged into a chip socket
with a DIP structure.
Both SMT and DIP are part of PCBA processing, but not all PCBA
plants have SMT and DIP post welding capabilities, and the
processing quality is uneven. When choosing a PCBA factory to
cooperate with, it is recommended to visit the factory site to see
the personnel technology, processing equipment, and overall
environment of the PCB factory.
PCB assembly requires knowledge of more than just PCB components
and assembly; It also requires expertise in printed circuit board
design, layout, PCB manufacturing, and end-product applications.
Shenzhen Sky-Win is a one-stop PCBA service provider - Our current focus on the PCBA one-stop supplier schematic design, software development, PCB Layout, a full set of material purchasing, SMT+DIP manufacturing, board direct supply and other OEM/ODM services.
