What is DIP Contract Manufacturing?

DIP, short for Dual In-line Package, refers to electronic components with two parallel rows of pins (commonly seen in IC packages). In Taiwan and China, any through-hole components inserted into the PCB (Printed Circuit Board) and soldered to secure them are generally referred to as DIP technology.
The formal technical term for this process is THT (Through-Hole Technology), which is the name used in countries outside Taiwan and China.
Advantages of DIP Technology Compared to SMT
Strong Soldering Reliability: DIP components are soldered through PCB through-holes, providing excellent mechanical strength.
Cost-Effective for Small Quantities: DIP processing requires relatively simple equipment and workflow, making it suitable for prototypes or small-batch production.
High Heat Resistance: DIP assemblies offer better thermal performance in high-temperature environments.
Easy to Repair: DIP components can be inserted or removed using basic soldering tools, making rework and maintenance more convenient.
DIP technology is widely used in fields such as industrial control, communications, and medical equipment. Common DIP components include resistors, capacitors, inductors, transistors, integrated circuits (ICs), relays, transformers, and more.
Typical DIP Manufacturing Process
Wire Routing: Prepare and organize DIP components in the required sequence for the insertion line.
Insertion: Manually DIP components into the designated PCB through-holes.
Soldering: The PCB is passed through a wave soldering machine, where molten solder firmly connects the DIP components to the PCB.
Inspection: Quality inspection is performed using Automated Optical Inspection (AOI) or visual checks to ensure soldering reliability.
Although DIP processing is relatively simple, it still requires proper technique and experience to achieve highly reliable results. If you need DIP contract manufacturing services, it is recommended to select a reputable and experienced DIP manufacturer.
SMTEK Electronic was established on June 6, 1987, specializing in SMT processing, SMT contract manufacturing, DIP processing, SMT sample/prototype pilot runs, and BGA rework. We primarily provide small-batch, diversified SMT services. Production quantities range from single prototype units (minimum one piece) to full-scale mass production, all supported by automated equipment. Throughout the years, our high-quality standards and fast delivery have earned strong customer recognition.
