Testing

In response to the growing demands on equipment reliability, PRINTOR now offers testing at various production stages. Implementation of in-production testing of electronic deliverables has become increasingly popular as end-users expect improvements in product quality. The testing significantly reduces the risk of finished product failure. The sooner the product weaknesses (e.g. defective components) are detected and eliminated, the lower is the risk of failure and loss.


Electrical testing of PCBs
See more
Electrical testing is intended to verify that the PCBs are free from shorting and circuit path discontinuities. It is based on testing the path resistance between specific test points and leakage resistance between each circuit path and the paths in the vicinity. The high precision and efficiency of production are backed by the latest processing machines: A5 Neo Flying Probe from ATG and PROBOT 880-05 from Mania Technologie.
AOI (Automated Optical Inspection)
See more
AOI enables verification of finished SMT quality by visual inspection of the components mounted on a PCB. The feed output by a digital camera sweeping the PCB under scrutiny is compared with the reference images of properly mounted electronic components. The AOI software package detects missing and incorrectly mounted components, as well as assembly and soldering defects.
Ionic purity testing (Ionograph)
See more
Each process of feeding electronic components to the assembly areas incurs the risk of component contamination. Ionic purity control is of utmost importance here. During ionic purity control, or ionograph testing, the presence of electrolytes which favour electrolytic migration is determined. These impurities may result in a failure of the contaminated electronic device. The determination is performed by testing the concentration of ions released during immersion of the tested circuit in a special solution.
In-Circuit Test (ICT)
See more
ICT can be performed following an SMT or THT operation. The objective is to determine the actual performance of the assembled components. ICT involves tapping the tested circuit by a measurement system using gold pins, installed on a dedicated ICT adapter. The ICT shows whether the mounted components meet their performance specifications and reveal any defective electronic parts. PRINTOR’s strength is the capability of fabricating proprietary ICT adapters and ICT software elements to reduce the ICT implementation time at a very competitive price.
Functional testing
See more
Functional testing is used to test the overall performance of the finished product or assembly. The functional test tools simulate the actual operating conditions to verify if the performance complies with the project specifications. The functional testing at PRINTOR is based on test systems or tools dedicated to specific products, either supplied by the customer or manufactured in house.
