Multi-signal sensing
Chemical, hydrogen and thermal channels evaluated together rather than in isolation.
Precision Hardware Engineering
Sensing. Heating. Engineering.

CircuitSprint delivers application-focused hardware engineering across four critical domains—Battery Safety, Temperature Sensing, Flexible Heating, and PCB/PCBA—built around the specific failure modes they are designed to prevent.
New Technology
Battery Protector
Detect battery venting
before it becomes a fire.
Know before it burns.
Battery Protector is a multi-signal early-warning module for lithium battery systems. It watches the chemical and thermal signatures that appear during the warning window before thermal escalation — and combines them into a single, corroborated alert.

VOC – H₂ evolution
Gas + thermal alert
Corroborated decision
No single sensor has to tell the whole story. Multiple signals must agree before escalation.
BMS compatible
Additive by design. Keep your existing protection layer — Battery Protector adds early warning on top.
Early warning
Designed to act during the warning window — before temperature becomes the dominant signal.

Keep your BMS. Keep your NTC. Add another layer.
Battery Protector is designed to sit alongside your existing protection — not replace it. It adds chemical and hydrogen context to a decision that today is often made on temperature alone.

01 Core Engineering Capabilities
Four Integrated Disciplines. One Unified Quality Standard.
We don't just assemble parts; we engineer solutions. Every domain adheres to a rigorous product discipline: define the failure mode, engineer against it, and validate it before production.
Domain 01
Battery Safety Systems
Advanced multi-signal early-warning hardware for lithium battery systems. Detects chemical and thermal signatures before thermal escalation occurs.
Explore Battery Safety
Domain 02
Precision Temperature Sensing
High-precision NTC, PTC, and platinum RTD sensors. Custom probe configurations engineered for demanding industrial, automotive, and medical environments.
Browse Sensors
Domain 03
Flexible Heating Solutions
Thin polyimide and silicone heating films with tightly controlled resistance. Engineered for curved surfaces, tight enclosures, and stable heat delivery.
Open Flexible Heaters
Domain 04
Advanced PCB & PCBA
Full-spectrum board fabrication and assembly. FR4, MCPCB, ceramic substrates, and turnkey PCBA services from prototype to series production.
Explore PCB & PCBA02 The CircuitSprint Advantage
Precision Engineering. Not Just Assembly.
We treat every component as a critical system. Electrical intent, mechanical fit, thermal behaviour, and production repeatability are reviewed together before anything is built.
Failure-Mode Driven Design
Every product starts with the question that matters — what failure are we preventing, and what signal arrives first? The engineering answers that, not the datasheet.
Repeatable Precision
Resistance targets, tolerance bands, and thermal behaviour are confirmed at file review. What you approve as a sample is exactly what you receive in production, batch after batch.
Proactive Design Review
We read your Gerber, drawing, and specifications together. If the electrical and mechanical intent conflict, we flag it before production — not after.
03 Development Lifecycle
From Concept to Production.
A transparent, four-step engineering workflow ensuring you know exactly what is happening at every stage of the program.
Design File Review
Comprehensive evaluation of drawings, Gerber files, resistance targets, and terminal methods for manufacturability and consistency.
Engineering & Quotation
Clear pricing with achievable tolerances, lead times, and testing scope. Typically returned within 24–48 hours.
Prototyping & Sampling
Rapid prototype built on the approved stack-up for real-world electrical and thermal validation before committing to production.
Production & Testing
Pilot or repeat batch production with electrical and insulation testing documented per lot before shipment.
04 Industries
Where our engineering fits.
Applications across industrial, automotive, consumer and instrumented products — wherever thermal and chemical behaviour matter.
Battery energy storage
E-mobility & EV packs
Motor & drive protection
Industrial automation
Medical devices
Telecom & backup power
Solar & renewable storage
Lab & analytical equipment

05 FAQ
Engineering Questions, Answered.
What does CircuitSprint actually manufacture?
We design and manufacture critical sensing and heating hardware across four domains: advanced battery safety modules, precision temperature sensors (NTC, PTC, RTD), flexible polyimide and silicone heaters, and complex PCB fabrication and assembly.
Do you support prototype quantities, or only production?
Both. Most programmes start with a prototype or sample build so you can
validate electrical and thermal behaviour on a real part. Once the sample
is approved, we scale to pilot or repeat production batches using the same
controlled files.
What files do you need for a quotation?
Gerber or ODB++ files, a mechanical drawing, stack-up or material
requirements, resistance target and tolerance, voltage and power
requirements, working temperature range, terminal or lead-wire method,
insulation and testing requirements, and your expected quantity.
Do you offer custom sizes and shapes?
Yes. Flexible heaters, sensors and safety modules are all built to your
mechanical drawing. Custom probe lengths, wire types, terminal styles and
connector options are all supported — reviewed case by case at file stage.
How long does a typical programme take?
Quotations usually return within 24–48 hours of receiving complete files.
Prototype lead time depends on structure and quantity. Production timing
is confirmed at order.
Do you test parts before shipping?
Yes. Electrical resistance, insulation resistance and continuity checks
are standard. Additional thermal or environmental testing can be included
for programmes that require it — specify the test plan at file review.
