Technology Support

Technical support based on field conditions

Surface treatment issues cannot be judged by chemical name alone. Pretreatment, plating bath management, filtration, rinsing, and post-treatment are reviewed together.

Diagnostic process

Inquiry details are organized from process information through follow-up checks to narrow down possible cause groups.

  1. 01Process information check

    Review the material, process sequence, chemicals, operating conditions, and recent changes.

  2. 02Plating bath analysis

    Check pH, metal concentration, temperature, agitation, filtration, and replenishment history.

  3. 03Defect cause classification

    Classify possible causes by the defect stage, location, frequency, and appearance.

  4. 04Condition adjustment

    Set the order for chemical replenishment, filtration, rinsing, and operating-condition adjustments.

  5. 05Follow-up and stabilization

    Confirm the result and recurrence status, then organize practical control criteria.

PLACHEM support scope

01

Process diagnosis

Current line conditions, defect timing, and recent changes are used to organize the check sequence.

  • Process check
  • Pretreatment and plating bath conditions
  • Rinsing and post-treatment
  • Recent changes
02

Analysis support

Plating bath and process control items are checked and connected to document requests or evaluation conditions when needed.

  • pH
  • Metal concentration
  • Temperature
  • Agitation and filtration
  • Replenishment history
03

Defect response

Pitting, adhesion issues, color deviation, white rust, and stains are separated by process-stage cause groups.

  • Defect photos
  • Location
  • Frequency
  • Operating conditions
04

New application support

For a new line or product application, application purpose, required quality, and evaluation criteria are checked first.

  • Application purpose
  • Process conditions
  • Evaluation criteria
  • Requested documents
