Dip is the abbreviation of dual in-line package. It refers to the device packaged in the form of plug-in, and the number of pins generally does not exceed 100. Often referred to as “dip welding” or “dip post welding”, refers to the soldering of dip packaged devices after SMT.
Dip soldering is a small-scale soldering process by which electronic components are soldered to a printed circuit board (PCB) to form an electronic assembly. The solder wets to the exposed metallic areas of the board (those not protected with solder mask), creating a reliable mechanical and electrical connection.
Dip soldering is used for both through-hole printed circuit assemblies, and surface mount. It is one of the cheapest methods to solder and is extensively used in the small scale industries of developing countries .
Dip soldering is the manual equivalent of automated wave soldering. The apparatus required is just a small tank containing molten solder. A PCB with mounted components is dipped manually into the tank so that the molten solder sticks to the exposed metallic areas of the board.
The difference between SMT and DIP
SMT is usually mounted on the surface of components without pins or short leads. It needs to print solder paste on the circuit board first, then mount it through the mounter, and then fix the device by reflow soldering. Dip welding is a kind of in-line package device, which is fixed by wave soldering or manual welding. Both SMT and dip are part of PCBA processing, but not all PCBA factories have the ability of post welding SMT and dip.
