プロセス

At our company, all work processes are in-house and integrated, allowing us to accept anything from prototypes to mass production.

All equipment supports integrated in-house production, for example, automatic plating lines, multilayer press machines, etc. are prerequisite to shorting set up times.From making a single prototype we deliver product development in a short time, supporting all the steps to low-cost mass production.

Steps to Delivery

  • 1
    Data Editing
    Editing of Garber data sent from clients, creating working films as well as NC data / Router Data etc.
  • 2
    Inner Layer Process
    Carrying out Inner layer pattern formation / etching inspection / blackening etc.
  • 3
    Vacuumed Multilayer Pressing
    Combining several inner plates to form a vacuum while pressing and applying heat from the oil heater.
  • 4
    Holing
    NC machines make holes (holes for inserting components and holes for electrical continuity).
  • 5
    Smear Removal
    Smear removal of epoxide resin generated when holing.
  • 6
    Copper Plating
    Copper plating is applied to the whole PWB surface (outer surface and inner hole walls) to electrically connect the front and back.
  • 7
    Hole Plugging
    When etching, in order to protect the copper plating in the holes from the etching solution, resin is embedded within the holes and hardened with UV.
  • 8
    Belt Grinding
    Smoothing of the surface to maximize adhesion of the etching resist.
  • 9
    Pattern Formation
    As an etching resist, dry film is laminated, then light exposure and developing are done.
  • 10
    Etching
    Other than the desired conductor pattern protected by the etching resist, unnecessary copper foil parts will be removed by the etching solution.
  • 11
    Intermediate Inspection (by AOI)
    Scanning the pattern optically, we inspect for the presence or absence of defects (breaks, short circuits, cracks, thick and thin circuits etc.).
  • 12
    Solder Mask
    When soldering electronic devices etc., permanent masking of the surface pattern for the purpose of protecting it from the external environment and to prevent soldering of unnecessary parts.
  • 13
    Symbol Mark Printing
    Printing of the position of parts to be mounted, the product name etc.
  • 14
    Surface Treatment
    Protecting copper foil areas on the surface of the PWB where resist is not applied.
    The methods are; Pb-free, Solder Leveling, OSP, and Gold Plating.
  • 15
    Blanking and Routing
    Blanking and routing with an NC router or a mold press.
  • 16
    Test
    •Dedicated jig: Conducts continuity test for mass production products.
    •Flying Probe Tester: Conducts continuity test by a moving probe for prototypes and small lot production products.
  • 17
    Inspection / Delivery
    The appearance etc. is checked, and items that pass inspection are packed into a box and delivered to the destination specified by the customer.
