ASSEMBLY ENGINEERING & CONSULTING

From concept to manufacturing, we strengthen the reliability of every bonding process.

Beyond supplying adhesives — we help electronics, medical, and precision manufacturers select, validate, and scale reliable assembly and bonding processes, and keep them stable in production.

• SECT_01 // ENGINEERING IMPACT

Quantifiable Production Results

Driving measurable improvements in yield, throughput, and reliability.

98–98.5%

FIRST PASS YIELD (FPY)

Typical first-pass yield we engineer toward on automated micro-assembly. In tight builds like lav-mic acoustic sealing, overflow control on UV-delay dispensing — and micro-welding — is the biggest FPY killer, so we tune it at the parameter level.

300–400

UPH (UNITS PER HOUR)

Per automated workstation. Line throughput is set by the bottleneck — usually cure time or RF acoustic calibration — so we break the ceiling by turning that station into a one-to-many parallel module.

<0.2%

FIELD FAILURE RATE

Under 2,000 DPPM. The common consumer-mic returns — battery-swell compression, capsule moisture ingress, drop-induced cracks — all hinge on dispensing structural strength and seal consistency.

8–12

NPI VALIDATION TIME (WEEKS)

About half our earlier timeline. Moving a proven product to a new automated process skips EVT and concentrates on PVT — extreme stress testing to find where equipment parameters drift.

• SECT_02 // APPLICATIONS

Vertical Solutions Matrix

Medical device components — cannulas, luer connectors and a syringe for assembly bonding.

Medical Devices & Wearables

Disposable Device & Wearable Bonding

BIOCOMPATIBILITY FOCUSLIGHT-CURE CA

Fast-fixture bonding and sealing for disposable medical devices and wearable housings — needle/cannula assembly, sensor and enclosure bonds. Light-cure cyanoacrylate chemistry (e.g. Loctite 4311), selected for biocompatibility-tested profiles and rapid line cure.

Precision Acoustics & TWS

ANC Acoustic Chamber Sealing

IPX7 WATERPROOFANC NOISE ISOLATION

Micro-gap filling and acoustic-chamber sealing for multi-mic ANC modules. A halogen-free, ultra-low-VOC outgassing formula eliminates diaphragm contamination and survives a 1.5 m drop onto concrete.

What We Do — Engineering Services

We don't just supply Henkel, DOWSIL and Shin-Etsu — we engineer the bonding process around them: selecting the right chemistry, validating it, and scaling reliable joints that stay stable in production.

Process Design

Dispensing, curing and fixturing designed around your line — not guesswork.

Failure Analysis

Bubbles, delamination, leaks or field returns? We find the root cause and fix the process.

Explore

Prototyping & Pilot

De-risk before mass production with lab-scale prototyping and pilot runs.

Explore

Material Substitution & Compliance

Second sources and drop-in candidates, proven equivalent to your process — with the RoHS/REACH paperwork mapped and traceable.
