Custom design and manufacturing
A key capability of JQL is custom design and prototyping. Its R&D team develops customer-specific components and subsystems and supports projects from technical specification and prototype development through to manufacturing.
JQL also has experience in ODM and contract manufacturing. Its manufacturing activities are partially vertically integrated, including in-house production of ferrite materials used for its products.
Quality and traceability
JQL integrates quality-control processes throughout several stages of manufacturing, from incoming quality control and in-process inspection through to final quality assurance.
- 100% electrical testing during Final Quality Assurance (FQA)
- Storage of associated electrical test data
- Batch-based material traceability
- Barcode-based material management integrated with ERP and MES systems
- Traceability of production steps and operator IDs through the MES system
- Quality analysis including root-cause analysis and corrective actions
JQL uses a range of inspection and test equipment for development and quality assurance, including X-ray systems, temperature-shock testing, ICT, anechoic chambers, PIM testing, power testing and vibration testing.
Certifications
For its Mundelein, Illinois location, JQL lists the following certifications:
- ISO 9001
- ISO 14001
- AS9100
JQL Technologies and EMCO Elektronik
EMCO Elektronik combines JQL's broad component portfolio with its own RF and microwave expertise. Customers therefore benefit not only from access to standard components, but also from technical support in selecting solutions suited to their application.
EMCO supports customers with technical specification matching, product selection and custom requirements. By combining JQL's custom-design capabilities with EMCO's technical consulting expertise, requirements that cannot be fully addressed using standard components can also be evaluated.
There are 22 products.
