SILVER / SILVER CHLORIDE PRINTING

Custom Screen-Printed Ag/AgCl Electrodes

JASPER manufactures screen-printed Ag/AgCl electrodes to customer-defined ink, substrate, contact geometry, cure and acceptance requirements.

Ag/AgCl is not a universal performance guarantee. JASPER prints and converts the approved construction; the customer validates electrochemical behavior, patient or sample contact, stability, intended use and regulatory evidence.

INK SYSTEM BOUNDARY

Specify the complete Ag/AgCl print system, not only the chemistry name

Printed silver/silver chloride performance depends on the exact ink, substrate, print geometry, dry or cure process, exposed area, interface chemistry and test method. Supplier review should connect each of those variables to a controlled document.

JASPER can manufacture to

Screen printing to customer-released electrode and trace artwork
Approved Ag/AgCl, silver, carbon and dielectric materials within quoted scope
Flexible substrate handling, registration, drying or curing and layer sequencing
Contact-window definition, die cutting, lamination and tail conversion
Lot-controlled production records and project-defined in-process inspection

The device team defines and validates

Electrode function, reference system and interface chemistry
Ink approval, material evidence and permitted supplier substitutions
Electrical or electrochemical test method, conditioning and acceptance limits
Patient, fluid or sample-contact requirements and contamination controls
Finished-sensor performance, shelf life, risk management and regulatory release

DESIGN ROUTES

Define where Ag/AgCl sits in the printed electrode architecture

The same chemistry label can serve different device functions. The artwork and BOM must distinguish active electrode regions, routed conductors, connector contacts and any additional printed or converted layers.

01 / BIOPOTENTIAL CONTACT

Exposed Ag/AgCl electrode area

A monitoring or electrophysiology design should define the exposed geometry, interface layer, edge clearance and relationship to the underlying conductor without assuming a generic impedance result.

02 / REFERENCE FUNCTION

Printed reference electrode pattern

Electrochemical sensor designs may specify a reference region with separate geometry and conditioning needs. Its behavior must be validated within the complete customer sensor.

03 / MULTI-MATERIAL PRINT

Ag/AgCl with silver, carbon or dielectric

Layer order, overlap, cure compatibility, print registration and exposed windows become critical when several ink systems share one flexible substrate.

PRINT-TO-TEST TRACEABILITY

Make ink, cure, geometry and acceptance criteria traceable

A defensible Ag/AgCl manufacturing definition should let the buyer connect a finished sample to approved material lots, artwork revision, print sequence and the exact inspection method used.

INK

Control the approved formulation

Record manufacturer, grade, storage, handling, lot traceability and any restrictions on substitution or shelf life.

Define deposit geometry

Artwork, screen, pass count and layer overlap should produce the customer-defined electrode and routing pattern.

CURE

Match process to substrate and ink

Time, temperature and sequence must fit the approved materials without implying electrochemical performance by process setting alone.

TEST

Use a project-specific method

Conditioning, fixture, solution or interface, measurement points, limits and sampling must be documented by the device program.

CUSTOMIZATION MAP

Engineering inputs for custom printed Ag/AgCl electrodes

Chemistry, geometry and process cannot be approved independently. The quote should identify which evidence and acceptance controls apply to the exact printed stack.

Ag/AgCl ink: Approved manufacturer and grade, solids or mixing instructions, storage, lot traceability and substitution control.
Base conductor: Silver, carbon or other underlying conductor, overlap geometry, layer order and interface requirements.
Substrate: Film family, thickness, surface treatment, dimensional stability, cure limit and conversion behavior.
Electrode geometry: Active outline, area, spacing, edge clearance, channel identity and connection to routed traces.
Dielectric windows: Protected routing, exposed Ag/AgCl regions, overlap, registration tolerance and visual boundary.
Contact interface: Customer-defined gel, fluid, membrane, dry contact or other interface and its coverage or conditioning.
Conversion: Die line, apertures, laminate, adhesive, liner, tail, reinforcement and assembly sequence.
Acceptance method: Conditioning, test environment, measurement setup, limits, sampling, records and deviation process.

BUYER QUESTIONS

Screen-printed Ag/AgCl electrode FAQ

Ag/AgCl terminology describes a material system, not a finished-device approval or guaranteed measurement result.

Can JASPER screen print custom Ag/AgCl electrode patterns?

JASPER can review customer-defined Ag/AgCl electrode artwork and print stacks when the specified ink, substrate, process limits, conversion and acceptance criteria fit our capability.

Can Ag/AgCl be printed over a silver conductor?

A multi-layer design may use Ag/AgCl with a customer-approved base conductor. Layer order, overlap, cure compatibility and exposed geometry must be defined and validated for the exact application.

Does JASPER choose the Ag/AgCl formulation?

JASPER can support a documented manufacturability review, but the customer must approve the formulation, supplier, material evidence and device-level suitability. No substitution is assumed.

Can the electrode be made on flexible PET?

Flexible film substrates may be considered when their surface, dimensional stability and cure limits fit the approved ink system and conversion process. The exact film is a project input.

What tests prove an Ag/AgCl electrode is acceptable?

There is no universal production test for every use. The customer must define conditioning, interface, fixture, measurement, limits, sampling and how the result relates to finished-device validation.

Are the samples shown certified for patient contact or diagnostic use?

No. The photographs are representative printed electrode constructions and do not identify a particular ink chemistry or approved medical use. Claims require exact product evidence.

Can JASPER maintain ink lot traceability?

Material-lot records and project-defined production documentation can be included when specified in the quotation, quality plan and purchasing requirements.

START WITH EVIDENCE

Have approved Ag/AgCl ink and electrode artwork?

Send the ink specifications, substrate, layer order, contact windows, conversion drawing, test method, documentation needs and forecast. JASPER will review printability and process control without inventing performance claims.
