SMT Assembly and THT Assembly

Here are two major PCB assembly techniques.

1. SMT (surface-mount technology): using an SMT stencil, the soldering paste is applied on the PCB to achieve the desired design, and the components are mounted or placed directly onto the surface of printed circuit boards.
2. THT (through-hole technology): a hole is drilled through the PCB, and then a component is placed over it on one side while wave soldering is applied on the other side.

Preparation for PCB Assembly

For PCB assembly, consumables and electronics parts as below are required:

1. Bare printed circuit boards
2. Primary electronic components
3. Depending on the type of the process of soldering, soldering components like solder balls, solder paste, solder bar, solder perform are required.
4. Flux for quote soldering
5. Assembly lines including reflow soldering machine, wave soldering machine, soldering station, SMT tools, testing/ inspection equipment, etc.
When the above things are provided, the PCB assembly process can start.

Process of PCB Assembly Services

Prototype PCB assembly is a non-linear process as quote concerns are involved. The procedure consists of basic steps as below.

Fine-Pitch Assembly Capability

• 23,500CPH chip (Laser centering/Optimum) and 18,500CPH (Laser centering / IPC9850).
• IC9,000CPH (Vision centering / MNVC option).
• From 0402(01005) to 33.5mm square components.
• The use of electronic double tape feeders enables the mounting of a maximum of 160 component types.
• High-speed, on-the-fly vision centering (when using both high-resolution camera and MNVC).
• Longer sized PWB in X-axis.
