Circuit Requirements
 The HYBRID SOURCES, INC. technical staff will work with you to define the electrical and mechanical requirements necessary to successfully implement your custom hybrid.
- Schematic diagram with required pinouts
- Parts list-part numbers (specific vendors), values, tolerances and power dissipation
- Definition of circuit function and complexity
- Electrical input/output characteristics and tolerances
- Final electrical test sequence and test parameters
- Critical component parameters and matching requirements
- Packaging configuration - size, pin outs, hermeticity, solderability, etc…
- Environmental and reliability constraints
- Trade offs and priorities - performance, size, reliability, costs, etc…
Hybrid Layout
Experienced designers are the key to translating circuit requirements into accurate thick film hybrid layouts.
- Substrate drawing prepared
- Layout created
- Assembly drawing created
- Resistor trim specifications created
- Customer approval requested
- Computerized artwork generated
- Artwork laser photoplotted
- Screens ordered
- Fixtures ordered
- Test specification prepared
- Customer provided with drawing package
Design Engineering
Electrical, mechanical, manufacturing and quality engineering disciplines combine to insure complete documentation, traceability and process repeatability.
