Capability Overview

Full-Chain Secondary Processing

Secondary processing covers the operations that turn molded parts into ship-ready assemblies: printing, coating, laser marking, dispensing, assembly, and coordinated plating.

SIKING uses these steps to keep finish requirements, assembly handoffs, and final inspection aligned inside one programme. Class 100K cleanroom spray coating is available for dust-sensitive coating work.

  • Screen printing, including back-side and conductive layers
  • Pad printing for curved or non-flat surfaces
  • Class 100K cleanroom spray coating
  • Laser marking and backlight-window etching
  • Dispensing, bonding, welding, and assembly
  • Coordinated plating via qualified partner

Process Capabilities

Secondary Processing — In Detail

Screen Printing

Front and back printing for legends, colour layers, and conductive features such as carbon pill or silver ink where required.

Applications: keypads, control panels, interface parts.

Pad Printing

Used for logos and legends on curved or irregular surfaces where flat screen printing is not the right fit.

Applications: curved housings, grips, formed parts.

Class 100K Cleanroom Spray Coating

PU, soft-touch, and wear-resistant coatings applied in a Class 100K environment to reduce contamination during the wet coating stage.

Applications: parts with dust-sensitive finish requirements.

Laser Etching & Marking

Used for backlight windows, logo marking, parameter engraving, and other permanent surface identification.

Applications: backlit keypads, marked housings, traceability features.

Dispensing & Potting

Machine-controlled dispensing for adhesives, sealants, and potting compounds, with insert placement where needed.

Applications: sealed connectors, potted assemblies, gasket-on-frame parts.

Assembly & Packaging

Bonding, welding, crimping, final assembly, and ship-ready pack-out handled to customer specification.

Applications: composite assemblies, finished kits, distribution-ready components.

Qualified Partner

Plating

Plating is coordinated through a disclosed qualified partner, then returned to SIKING for final inspection and pack-out.

Best Suited For

  • Finished goods that need decoration, marking, or colour coding
  • Keypads and panels with backlit windows or conductive layers
  • Parts with dust-sensitive coating requirements
  • Assemblies requiring bonding, welding, potting, or final pack-out
  • Programmes that want one owner for post-molding operations

Not Suited For

  • Large-format decorative printing outside keypad and interface scale
  • Specialist Class A cosmetic finish requirements outside the coating scope
  • Processes that add no functional or commercial value to the finished part
  • Programmes that require a different specialty finishing route than coordinated plating
Common Questions

Secondary Processing — FAQ

Why does cleanroom spray coating matter for dust-sensitive parts?
+
It reduces contamination while coatings are wet, which matters when the finish must stay clean and consistent.
What is a carbon pill, and when is it used?
+
It is a conductive printed feature on the underside of a silicone key that closes the circuit on the PCB when pressed. Silver ink is reviewed when lower resistance is required.
Can SIKING deliver fully assembled, packaged, and labelled goods for direct distribution?
+
Yes. Assembly, packaging, and labelling scope are aligned during programme setup so goods can ship ready for distribution or downstream integration.
