PCB assembling

Work Preparation

As a first step, after the order has been received, the work will be planed and the components purchased. There are instructions for each project, therefore, the (process) information required for the work is clearly recorded. Any desired additional audits are planned in cooperation with the Purchasing Department. Changes to the PCB (Printed Circuit Board) and BOM (parts list) are only made after consultation with and the approval of the client. At the SMD and Through-hole departments, the (electronic) components will be placed and soldered to the PCBs.

SMD (Surface Mounted Devices)

The solder paste is applied to the bare board by the DEK Horizon 02 screen printers. Our modern Samsung SM411, SM421, SM482 and SM471Plus SMD placement machines automatically place the components on the board. The Soltec My- Reflow ovens, which have 8 heating and 2 cooling zones, does the soldering. The Viscom (3088 AV AOI) automatically performs an optical inspection and the board is also inspected visually. We are also able to use the Dage X-ray Inspection System (XD7500VR) to inspect specific soldered joints.

SMD - Inspection

The board is inspected after the SMD components have been placed and soldered to the board. There are three possibilities:

  • Visual
  • Automatic Optical Inspection (AOI)
  • X-ray for BGAs, QFNs, etc.
Conventional - Overview of activities

After completion of the SMD production phase, the Conventional Department can perform the following activities:

  • Component bending
  • Component cutting
  • Manual component placement
  • Mounting heatsinks, wiring, etc.
  • PCB soldering: manual, wave, selective
  • Loading software
  • Functional testing
  • Adding serial numbers
  • Packing
  • Readying for shipment

It is also possible to perform activities related to final assembly / systems / mechatronics such as climatic testing, burn-in, cleaning, coating and potting of PCBs or mounting in an appropriate enclosure.
