Hardware/Electronics Design Engineer

Hardware / Electronics Design

Before each device is ready to use, it must go through some steps, one of the most important is a finished, tested and fully functional PCB/FPC that follows IPC standards

Project process

Requirements design

As a first step our team makes technical requirements. After this, we select all the main components, agree on basic concepts with the customer and make a block diagram
Alternate Text

Schematic design

Our engineer(s) makes schematic design based on the selected components and technical requirements
Alternate Text

Schematic design review

The engineer sends the designed schematic to the reviewer (a hardware developer, that does a schematic review). The reviewer makes a report (use our standard template with a checklist) and sends it back to the first engineer to make corrections
Alternate Text

PCB layout

Printed circuit board (PCB) design brings electronic circuits to life. Our engineer(s) makes a PCB layout design that combines component placement and routing to define electrical connectivity on a manufactured circuit board using layout software
Alternate Text

PCB layout review

The engineer sends the PCB files to a reviewer. The reviewer makes a report (use our standard template with a checklist) and sends to the first engineer back to make corrections
Alternate Text

Manufacturing

Our team creates a bill of materials (BOM) that contains a list of the materials, components, parts, and those quantities needed to manufacture prototypes. After we order components(the USA, EU and China) and PCBs. We assemble samples in our labs(usually 4-6 units) or order them from China/EU/Taiwan/The USA
Alternate Text

Device Bring Up and testing

Our engineer(s) verifies the signals, antenna matching (if it has an RF part), loads test firmware, and runs a test (power management, power distribution, checks all signals). If there are any issues in current version, the engineer fixes them by soldering some additional components or wires (find ideally all issues and fix the solution in the Alpha version)
Alternate Text

Make Errata document

Our engineer(s) makes one important document that has a list of issues with a detailed description. It needs to fix the schematic and PCB in the next revision
Alternate Text

Schematic design modifications

Based on Errata document our engineer fix the schematic
Alternate Text

Schematic design modifications review

Our engineer sends out the updated schematic for review, the reviewer checks: the Errata document, the updated schematic and makes the review report and sends it to the first engineer to fix issues
Alternate Text

PCB layout modifications

Based on Errata document our engineer fixes the PCB
Alternate Text

PCB layout modifications review

Our engineer sends out the updated PCB for review, the reviewer checks: the Errata document, the updated PCB and makes the review report and sends it to the first engineer to fix issues
Alternate Text

Manufacturing

Updates BOM, order components, assembles samples (similar steps to the Alpha version
Alternate Text

Device Bring Up and testing

Our engineer(s) verifies the signals, antenna matching (if it has an RF part), loads test Firmware, and runs a test (similar steps to the Alpha version)
Alternate Text

EMC and precertification testing

At this stage, we check our device and do pre-testing in our laboratory, use the spectroanalyzer up to 24 GHz with different antennas and get the first result of the testing. If there are any issues with parasite harmonics, we try to fix them in our lab until it works. As we get everything working we rent a certificated laboratory for EMC and run tests
Alternate Text

Make Errata document

We update the Errata document if have issues
Alternate Text

Schematic design modifications

Based on Errata document our engineer fixes the schematic
Alternate Text

Schematic design modifications review

Our engineer sends out the updated schematic for review, the reviewer checks: the Errata document, the updated schematic and makes a review report and sends it to the first engineer to fix issues
Alternate Text

PCB layout modifications

Based on Errata document our engineer fixes the PCB
Alternate Text

PCB layout modifications review

Our engineer sends out the updated PCB for review, the reviewer checks: the Errata document, the updated PCB and makes a review report and sends it to the first engineer to fix issues
Alternate Text

Manufacturing

Update BOM, order components, and assemble samples (similar steps to the Alpha/Beta version)
Alternate Text

Device Bring Up and testing

Our engineer(s) does verification of the signals, antenna matching (if have an RF part), loads a test Firmware, do tests and etch (similar steps to the Alpha/Beta version)
Alternate Text

EMC and precertification testing

We rent a certificated laboratory for EMC and run tests
Alternate Text

Run pilot

Manufacture 20-50 samples for field testing
