Board Design

Delivering the Ultimate Hardware Experience, Everytime

Board design always demands “Do it Right the First Time” simply due to the lack of the flexibility to modify/change/upgrade the design at a later stage or even after production, unlike the software. A Revision of PCB can cause huge delays in schedule and huge expenditure in proto builds, thereby missing the targeted Cost as well as Time-To-Market Window by an unacceptable Margin.

Black Pepper Technologies’ Board / System Design Group believes in Correct By Construction Principle and has the capability to design and develop end to end products right from the concept till the production, abiding by the said Principle. The team has vast experience in high speed, high complex designs which involve several modules that are integrated to form a single product. The team has excellent exposure to develop products as per various regulatory / statutory compliance standards, inter alia, FCC, CISPER, CE, RTCA DO-160, MIL-461 and ISO26262. We also provide support in compliance testing at certified labs along with the final certifications / markings of the product as required. The team is capable of developing the Hardware using any industry standard tools like Cadence Orcad, Concept HDL, Altium, Allegro etc. We have tie-ups with several PCB Fabrication and PCB Assembly vendors and can take up the entire prototyping to any small/large scale manufacturing with a dedicated in house SCM (Supply Chain Management) team.

We offer swift product development for several industries like IoT (Internet of Things), Consumer Electronics, Industrial Automation, Wireless & Telecom, Defence and Automotive.
