One of the main advantages of through-hole parts is their strength.
The surface mount parts are soldered to a metal pad, and while this
provides a strong bond between the parts and the circuit board, it
is not nearly as strong as a through-hole connection. With the
through-hole lead through a hole and the solder up and through the
core suction, the part has a more robust solder spot. This strength
is critical for switches, battery holders, connectors and other
interface components that would be under a lot of stress during
normal use.
Another through-hole advantage is suitable for designs with large
amounts of power. High-current circuits require large and sturdy
soldered connections to the circuit board for wiring, and
surface-mounted solder points may not be sufficient. In addition,
high power components can also be very heavy, especially if
radiators are used. Not only do these parts require the strength we
mentioned above, but the heat required to weld them into place may
be too much for surface mount solder spots. In addition, for the
reasons we have just listed, many larger components for high power
applications simply cannot be packaged in an equivalent surface
mount.
DIP
1,The process of DIP processing is: putting in the hole →AOI→ wave
soldering → cutting pin →AOI→ correction → washing → quality
inspection.
2,After wave soldering, The products will be will scanned by AOI
equipment to ensure that no error occurs.
Single-side mixed loading process
Incoming material detection => PCB side A screen printing solder
paste (spot patch glue) => patch => drying (curing) =>
reflow welding => cleaning => plug-in => wave soldering
=> cleaning => detection => repair
Double-sided mixed loading process
A: Incoming material detection =>PCB B spot patch glue =>
patch => curing => turn over =>PCB A side plug-in =>
wave soldering => cleaning => detection => repair
Stick before insert, suitable for SMD components more than separate
components
B: Incoming material detection => PCB side A plug-in (pin bent)
=> turn over => PCB side B patch glue => patch =>
curing => turn over => wave soldering => cleaning =>
detection => repair
Insert before paste, suitable for separated components more than
SMD components
