Capabilities
What we deliver
Yield analysis
Pareto analysis of AOI, ICT and functional-test failures against a defined denominator, with targeted fixes to the design, stencil, profile or test.
Root-cause and field-failure analysis
Failed units, symptoms and test logs analysed against the affected population, then a corrective change released with traceability to the product revision.
Obsolescence response
Qualified alternates for end-of-life or unavailable parts, last-time-buy assessments and the layout or firmware changes a substitution needs.
Cost-down redesign
BOM, layer-count, panel and test-time reductions assessed for their electrical, mechanical, firmware and compliance impact before release.
Production test fixtures
Bed-of-nails and functional test jigs with Python or LabVIEW test executives, parametric logging and pass/fail limits agreed with your contract manufacturer.
ECO and regression release
Each change handled as an engineering change order with regression tests, so the production release stays traceable.

Planning
Scope and cost
Start with a non-confidential summary of your product and the milestone you need to reach next.
What to include in a sustaining engineering brief
Production support begins with a reproducible problem and a traceable product revision. Yield improvement, component obsolescence, BOM cost reduction and field-failure analysis need different evidence and acceptance measures.
Inputs for your project brief
- Product revisions, firmware builds, BOM and supplier change or obsolescence notices.
- Failure symptoms, affected quantity and total population, test logs and available failed units.
- Target cost or yield, production schedule, approved change process and retest requirements.
Choose the scope for your next milestone
- If the next step is diagnosing the design, start with an electronics design review.
- If a change creates a new production release, include manufacturing handoff support.
Agree the deliverables and acceptance criteria
Agree a baseline and measurement window before judging a yield or cost improvement. Document root-cause evidence, approved changes, regression results and release traceability. Treat a component substitution as an engineering change with electrical, mechanical, firmware and compliance impacts to assess.
Agree confidentiality arrangements before sharing proprietary design files.

FAQ
Frequently asked questions
We design bed-of-nails ICT fixtures, functional test jigs, and custom pogo-pin interfaces optimized for reliable contact, fast board loading, and long service life in high-volume environments. Our fixtures incorporate guided alignment, pneumatic actuation for consistent probe pressure, proper grounding for signal integrity, and modular probe plate construction for easy maintenance.
We support your contract manufacturer's line setup rather than running a line ourselves: reflow profile review, selective soldering parameters, first-article inspection procedures, operator work instructions, ESD control requirements and test-station design, with throughput modeling for target cycle times.
We employ a structured methodology starting with defect data collection and Pareto analysis, followed by root cause investigation using DOE for process parameter optimization. Common improvements include solder paste stencil aperture tuning, reflow profile zone-by-zone optimization, component moisture sensitivity management, and PCB pad design modifications, with first-pass yield targets agreed per product.
We configure AOI systems with inspection programs tailored to each product's critical defect types, setting detection thresholds that balance escape rate minimization against false call rates. Our AOI integration includes golden board library creation, solder joint classification algorithms, component presence and polarity verification, and statistical feedback loops to identify process drift trends.
We develop functional test systems covering power-on self-test, stimulus/response measurements for analog and digital circuits, communication interface validation, sensor calibration routines, and firmware loading. Our platforms use commercial instruments and custom interface boards controlled through LabVIEW, Python, or C# test executives, with parametric data logging and automated pass/fail reporting.
We develop ICT programs targeting component-level measurements including resistance, capacitance, inductance, diode junction checks, and IC pin connectivity verification. Our approach includes test access analysis during PCB layout to ensure adequate test pad placement, fixture nail count optimization, and boundary scan integration for BGA and fine-pitch devices where physical probe access is limited.
We implement analytics pipelines aggregating test results, defect data, and process parameters into unified dashboards showing real-time yield trends, defect Pareto charts, and SPC control charts. These analytics enable proactive quality management by detecting process shifts before yield excursions, correlating defects with specific component lots, and providing traceability data for field failure investigation.
End-of-line testing validates the fully assembled product against customer-facing specifications, including functional performance, safety checks (hipot, ground bond), cosmetic inspection, label and packaging verification, and firmware version confirmation. We design EOL sequences that are comprehensive yet time-efficient, typically completing in under 60 seconds for consumer products with automated data logging for traceability.
Our troubleshooting follows a structured diagnostic process starting with defect symptom categorization, timeline correlation with process or material changes, and statistical analysis to distinguish random from systematic failures. We use thermal imaging, X-ray inspection, cross-sectioning, and microsection analysis to identify root causes and implement corrective actions with effectiveness verification.
We conduct process validation through IQ (Installation Qualification), OQ (Operational Qualification), and PQ (Performance Qualification) protocols. Deliverables include Cpk process capability studies, measurement system analysis for test equipment, and a validated process window document defining acceptable operating ranges for all critical parameters.
Burn-in testing is recommended for products with high reliability requirements such as medical, aerospace, automotive, and critical infrastructure applications, where it screens out infant mortality failures. We design programs specifying temperature stress levels, voltage and signal stimulus conditions, and test duration based on target failure rate reduction, using static or dynamic approaches depending on the cost-reliability tradeoff.
Essential metrics include first-pass yield (target above 95-99%), DPMO (target below 500 for mature processes), test escape rate (target below 100 PPM), customer return rate (target below 0.5%), and OEE (target above 85%). We help establish baselines, set improvement targets using Six Sigma methodology, and implement SPC-driven control systems that trigger investigation when metrics deviate.
Working with Rapid Circuitry
How much does a project cost, and how is pricing structured?
Each project is quoted as a fixed-scope proposal: a statement of work with milestones, deliverables and pricing, sent within 3–5 business days of the discovery call. The price depends on the requirements, how mature the design is, technical complexity, the number of prototype iterations and the validation scope. Longer engagements can also run as a retainer or a hybrid of both. For budgeting before you contact us, our hardware development cost benchmarks and the PCB design, firmware and IoT cost guides give indicative ranges with their assumptions stated. They are planning ranges, not quotes.
How long does a project take?
It depends on the scope and on what already exists when we start. As planning ranges from our cost benchmarks: a single PCB layout takes 2–6 weeks per board and embedded firmware 4–16 weeks. A connected (IoT) product takes 3–12 months from concept to a production-ready design, and a regulated medical device 12–24 months to a 510(k) submission-ready package; from idea to mass production, a typical connected product takes 9–18 months. The proposal sets out a dated milestone plan, and you receive weekly progress updates during the project.
Who owns the intellectual property?
You do. Our contracts assign the intellectual property in the project work product (schematics, PCB design files, firmware source code and documentation) to you on payment, and we hand over the source files, not only fabrication outputs or compiled binaries. The exact terms are set out in the signed agreement for each engagement.
Do you sign NDAs?
Yes. We sign a mutual NDA before any technical discussion of your project. Send your standard NDA or use ours; we return it signed within one business day.
Can you work with clients in the US, Europe and Japan?
Yes. We are based in Hyderabad, India, and work with product teams in India, the United States, the United Kingdom, Germany, Japan, Australia, the Middle East and other markets. Our office hours are 10:30–19:00 India Standard Time (UTC+5:30), Monday to Saturday, and we schedule design reviews across time zones, typically from US Pacific to Central European time. Japan is 3.5 hours ahead of India, so our first four hours overlap the Japanese afternoon. Prototypes and documentation ship by international courier such as DHL or FedEx. Our hardware outsourcing guide covers what to agree before an international project starts.
Do you hand off to manufacturing, and which contract manufacturers do you work with?
Yes. We prepare the manufacturing release package — fabrication and assembly drawings, the BOM with approved manufacturers, programming files and test specifications — and hand it over to the contract manufacturer (EMS) you choose. If you have not chosen one, we help you evaluate candidates through technical capability assessments and a pilot build. See manufacturing support.
Are you ISO 9001 or ISO 13485 certified?
No. Rapid Circuitry does not hold ISO 9001, ISO 13485 or other certificates. Our processes are aligned with ISO 9001:2015, and we design products to the requirements of the standards that apply to them — for example IEC 60601-1 and IEC 62304 for medical devices (with design documentation structured so your ISO 13485 quality system can absorb it) and IEC 61000 for EMC — and we specify IPC-A-610 workmanship classes for assembly. We prepare the product and its documentation for certification testing at accredited laboratories; the certificate or approval is issued for your product by the laboratory, notified body or regulator.
What do you need from me to start?
A short, non-confidential description of the product and what it must do (sensors, connectivity, on-device processing), the target production volume and unit cost, the markets and regulations it must meet (for example FDA, CE or FCC), your timeline, and what already exists: a concept, a proof of concept, schematics, PCB files or firmware. After the NDA, the next step is a 30-minute discovery call with the engineers who would work on the project, followed by the fixed-scope proposal. Send a project brief to begin.
