How Does SMT Assembly work?

How Does SMT Assembly work?

We use our customer’s gerber files to program the machine, and these together with the bom specify the components we load into the machine. The solder paste is evenly applied to the PCB using a paste stencil before the PCB is loaded into the SMT machine. The internal robot selects the specified components according to the program, identifies and orientates each one before and placing them in their allotted locations. The populated PCB travels on a conveyor through a reflow oven to cook the solder.

Advantages of SMT

Advantages of SMT

  • A higher number of components fit into the same space (when compared to through hole).
  • A Simpler and faster assembly process shortens the overall production time and therefore cost.
  • The process will automatically correct minor placement errors.
  • The PCB can be a lot smaller than an equivalent through hole board
  • The internal robot automatically places components onto each side of the PCB.
  • Less holes are needed in the PCB.

Automated Equipment

Surface Mount Machines

SMT Machines

We have several automated pick and place machines, all of which can place fine pitch SMT components at high speed onto single or double sided PCBs. Each one of our machines can hold approximately 60 different component types, depending on the component shape and size.

Reflow Oven

Reflow Oven

Our reflow oven has several temperature zones to enable gentle heating and cooling of the PCBA. We program both the temperature and speed through each zone based on the PCB material and the components on the board. This care and attention to detail is to ensure the quality and joint integrity on each SMD assembly.

AOI

AOI

Our AOI (Automated Optical Inspection) machines inspect each surface mount assembly, looking at the markings on each component. This inspection confirms that the type, value and orientation of the component match the pre-programmed values.
