Engineering Scope
Low-leakage hardware and PCB were developed to solve specific engineering problems in low-power projects. The work starts from the customer's existing design and business requirements, checking static paths, protection devices, level conversion and device quiescent current; delivering schematic diagrams, PCB source files, BOM, manufacturing files and node current records according to the agreed modules.
Check input with baseline
Check the schematic diagram, PCB, BOM, power supply range, interface connection and environmental requirements, and clarify the measurement and modification range.
Implementation and adaptation
Check static paths, protection devices, level translation and device quiescent current, and record solution trade-offs and dependencies.
Target environment joint debugging
Measure the power rail and the complete device separately, review the current changes after each interface is connected, and confirm the business behavior after parameter changes.
Document and record delivery
Provide schematics, PCB source files, BOM, manufacturing files and node current records, describing versions, build or usage methods.
Project Workflow
- Input confirmation: schematic diagram, PCB, BOM, power supply range, interface connection and environmental requirements.
- Implementation method: Check the static path, protection devices, level conversion and device quiescent current.
- Stage review: measure the power rail and the complete device separately, and review the current changes after each interface is connected.
- Engineering Delivery: Schematics, PCB source files, BOM, manufacturing files and node current records.
Design Conditions and Functional Limits
The specific path needs to be located first. Device selection, bias resistors, protection and interface connections may all be relevant, and the scope of rectification will be determined by measurement evidence.
Special services take the agreed module as the implementation boundary. When hardware modifications, third-party agreements, overall platforms or external tests are involved, the interfaces, workload and responsibilities are confirmed separately, and local modifications are not directly used as conclusions on the performance of the complete device.
Project Inputs
- Schematic diagram, PCB, BOM, power supply range, interface connection and environmental requirements.
- Existing prototypes and reproducible problems, or new project functionality and power consumption targets.
- Modified design, source code and third-party dependencies are allowed; functionality and compatibility need to be maintained.
- Delivery list, target environment, sample scope, project milestones and acceptance methods.
Delivery and Acceptance
| Delivery content | Check method |
|---|---|
| Schematic, PCB source files, BOM, manufacturing files and node current records | Check the editability, version, usage instructions and dependencies by file list. |
| Implementation verification | Measure the power rail and the complete device separately, review the current changes after each interface is connected, and retain the corresponding working conditions and results. |
| Comparison of functions and power consumption | Fixed applicable hardware, software, battery, temperature and business cycles, accounting for changes in conditions and their impact. |
| Reproduction and follow-up maintenance | Provide build or run steps, known limitations, parameter ranges, and uncovered cases. |
Frequently Asked Questions
Can only modifying the layout of PCB reduce standby power consumption?+
The specific path needs to be located first. Device selection, bias resistors, protection and interface connections may all be relevant, and the scope of rectification will be determined by measurement evidence.
What information do I need to prepare before starting the project?+
This work focuses on the schematic diagram, PCB, BOM, power supply range, interface connection and environmental requirements. When the data is incomplete, first determine the scope that needs supplementary testing or sorting out, and then proceed to implementation.
Can it be implemented together with the complete device development project?+
It can be used as a work package in the overall project, or it can be implemented separately for existing products. It is necessary to explain the interfaces with other modules, versions and final machine verification responsibilities.
