Testing and quality
At Hokami, quality is an integral part of every manufacturing process. Inspection takes place at every stage, from incoming materials through solder paste application and SMT and THT assembly to final assembly, functional testing and dispatch. Our multilayer quality control system ensures high reliability, repeatable production and the highest quality for every electronic assembly.
Standards
Inspection throughout manufacturing
Manufacturing processes are managed in accordance with IPC-A-610, while PCB cleanliness follows IPC-CH-65B recommendations. All inspection and testing processes are tailored to the customer’s specific requirements and the characteristics of the product.
Quality is verified from the first manufacturing operations. We check solder paste application, component placement accuracy, solder joint quality, electrical properties and the functionality of the finished product. Every step is designed to detect deviations as early as possible and prevent them from affecting the final product’s quality.
Our quality system includes
SPI (Solder Paste Inspection) – checking solder paste application quality.
AOI (Automated Optical Inspection) – automated inspection of component placement and solder joints.
BGA inspection using an endoscopic camera.
In-Circuit Test (ICT) – electrical testing of assembled components and connections.
Functional testing (FCT) to customer requirements.
Programming electronic assemblies.
Burn-in testing to verify long-term reliability.
High-voltage testing (HV Test) for AC and DC applications.
Mechanical testing of buttons, switches, toggle switches and reed relays.
Optical measurement of LEDs and displays, including light intensity and wavelength.
Testing sound-producing components (Buzzer Test).
Visual inspection of component dimensions, height and position.
Testing equipment
Automated optical inspection (AOI)
Automated optical inspection provides fast, precise checks of PCB assembly quality. AOI systems verify component presence, orientation and position as well as solder joint quality, significantly improving manufacturing reliability.
Testing equipment
1× SAKI BF-Comet-E
4× SAKI BF-Sirius
1× SAKI 3Di-LS2-L
Endoscopic camera for BGA package inspection
In-Circuit Test (ICT)
Electrical testing checks individual components, connections and electrical parameters before functional testing begins.
Testing equipment

Functional testing
Functional tests simulate real operating conditions and verify that the product works correctly. We prepare individual test scenarios according to customer requirements and the specific application.
Examples include:
Comprehensive functional testing of electronic assemblies
Communication tests (I²C, RS232, Bluetooth)
Firmware programming
Burn-in testing
High-voltage testing (AC/DC)
Mechanical testing of controls
Optical testing of LEDs and displays
Testing sound-producing components
Quality assurance
Production traceability
Every electronic assembly can be traced throughout manufacturing. Our traceability system records materials, production batches, process operations, test results and individual manufacturing parameters. This ensures maximum manufacturing transparency and meets the requirements of customers in industries with demanding quality standards.
ESD protection
All manufacturing and testing takes place in an ESD-protected environment. Strict electrostatic protection rules minimise the risk of damage to sensitive electronic components during manufacturing, handling and testing.
Calibration of measuring equipment
All measuring and testing equipment is regularly calibrated in accordance with our internal quality management system. This ensures measurement accuracy, repeatable results and the long-term reliability of all inspection processes.
Test fixture development
For specific projects, we design and manufacture our own test fixtures and automated test stations. This allows us to tailor testing to individual customer requirements and provide the highest level of inspection for every product.
