What is DIP and SMT?

SMT stands for Surface Mount Technology, which is currently the most widely used process in the electronic assembly industry. This technology involves mounting surface mount components, such as resistors, capacitors, and single-chip microcomputers, on the surface of a circuit board or other substrates. The components are soldered and assembled using methods such as reflow soldering or dip soldering.

During production, SMT materials such as surface mount components are soldered using surface assembly technology, typically on the internal surface of mobile phones. They go through several processes, such as reflow soldering or dip soldering, to ensure proper assembly.

Solder paste printing: The solder paste is printed on the surface of our PCB board by hand or machine.

Component placement: use a manual or placement machine to mount SMT components on the printed PCB board.

Reflow soldering: through the process of gradual heating, the solder paste is melted at a certain temperature, and the mounted components and the PCB board are effectively soldered together to achieve reliable electrical performance.

Difference Between DIP vs SMT

The difference between DIP vs SMT

The SMT processing method has several advantages. Components processed by this method occupy minimal space, have a high production efficiency, and experience fewer problems.

DIP, which stands for Dual In-line Package, refers to a device that comes packaged in a plug-in form. The number of pins generally does not exceed 100. The frequently mentioned "dip soldering" or "post-dip soldering" refers to the soldering of dip-packaged devices after SMT.

DIP materials mainly consist of in-line components such as electrolytic capacitors on computer motherboards, power transformers, and transistors. These are mainly processed by manual welding or wave soldering. The processing technology for DIP materials is different from that of SMT materials. The cost of DIP materials is also much higher than that of patch materials. Currently, most of the welding industry is based on SMT material welding, with only a small number of dip components. Some special products, such as power supplies, may still use dip components.

SMT patch components are generally mounted with no-lead or short-lead surface assembly components. To mount these components, it is necessary to print solder paste on the circuit board, mount it through a placement machine, and then fix the device through reflow soldering. DIP welding is a direct-insertion packaged device, which is fixed by wave soldering or manual soldering.

DIP vs SMT is part of the PCBA processing. However, not all PCBA factories have dip vs SMT post-welding capabilities, and the processing quality is also uneven. When choosing a PCBA factory for cooperation, it is recommended to go to the factory for on-site inspections to see the factory personnel skills, processing equipment, and the overall environment of the factory.
