STEHA-Elektronik stands for careful and precise manufacturing with comprehensive process reliability. All production steps and processes are subject to strict and continuous quality management. Expert knowledge, long-term experience as well as high-quality material and modern technology are the corner stones of our products. Consistent application of quality assurance according to ISO 9001 is not just a formality for us, but rather stems from our desire to always strive to fulfill the high demands of our customers.

Unsere Leistungen umfassen unter anderem:

• Quality checks before production begins:
  • Verifying data is complete and unambiguous
  • Design for Manufacturing support possible for external developments, to achieve best quality and cost/benefit ratio
  • Identification of alternative components if necessary
  • Communication and support in reacting to product change notifications, sourcing of hard to get or obsolete components where alternatives are not possible (Obsolescence Management)
  • Specimen testing
• All production in ESD controlled environment and by trained workers
• Manual and Automated Optical Inspection (AOI device):
  • Presence/absence check, tomb stone detection
  • Soldering check (too little/too much solder, bad solder joint, solder bridges etc.)
  • Correct positioning (orientation, polarity, offset etc.)
  • Value checking if possible (text/colors/marker)
  • any other defects (e.g. contamination)
• End-of-line ICT & functional testing with custom developed testing devices (e.g. bed of nails adapters and/or electronics on PCB):
  • Short circuits
  • Functional testing of protection components
  • Verification of voltages under defined load
  • Programming of testing software for functional tests of CPU/MCU/ICs
  • Verification of precision and noise of analog components according to specification
  • Burn-In tests
  • Flashing of production software (including verification)
• Isolation test for complete devices with rubber connectors
• Documentation of test results
• Support with pre- and certification tests EMC
• Other tests for special cases
