Inside a CGM SKD Kit: Components, Assembly and Quality
2026-10-26 · Verid Bio
A CGM SKD kit is not a box of loose parts — it is a defined set of components that have been produced, tested and calibrated at the factory, leaving only the final assembly, branding and registration to your facility. Understanding exactly what is in the kit — and what is deliberately left out — is the first step to evaluating any SKD partnership. (Start with what CGM SKD means if the term is new.)
This guide walks through the standard CGM SKD kit component by component, explains why each part ships the way it does, and what the assembly step actually involves.
The principle behind the kit
The kit is built around a single idea: the engineering-intensive, accuracy-critical work stays at the factory, and the market-facing, locally-relevant work moves to you.
Electrode fabrication, membrane coating, calibration and final quality control are exactly the steps that make a CGM accurate — and the steps that are hardest to reproduce locally. They stay under engineering control. What ships to you is a sensor that is already finished and validated; your team adds the housing, the packaging and the registration.
Component by component
1. Sterilized sensor kit
The sensing element at the heart of the product. Produced, calibrated and released on the manufacturer's line, with functional screening on every batch. This is the component that carries the accuracy claims, and it is the one your local registration will scrutinise most.
2. PCBA transmitter
The electronics that read the sensor signal and convert it into a radio transmission to the companion app or receiver. It ships tested, so the data path is proven before it reaches you.
3. Battery
The power source sized for the full wear period. Included and specified so the transmitter runs reliably for the device's intended life without your team having to qualify a power source.
4. Applicator main body
The mechanism that inserts the sensor. Precision-engineered so that insertion is repeatable and comfortable — the part of the experience a patient notices immediately.
5. Applicator bottom cover
The mating part that completes the applicator. Together with the main body it forms a closed, sterile insertion system ready for final assembly.
6. Packaging and documentation
Unbranded packaging, manual artwork and the registration file (performance verification, quality certificates, design and manufacturing information). This is where the product becomes yours — your brand, your language, your local IFU.
What the kit deliberately does not include
Just as important as what is in the kit is what is left to you — because that is the point of the model:
- Final assembly. Connecting the components is a guided snap-fit operation with SOPs and training, done in your controlled environment.
- Branding. The packaging, manual, app localisation and labelling carry your name.
- Local registration. You hold the approval; the manufacturer supplies the technical file it depends on.
How assembly actually works
The assembly step is engineered to be repeatable by a trained team rather than by a specialised engineer. Component connections use guided snap-fit designs, often with audible confirmation, so a team can establish a stable routine during enablement and then improve cycle time with volume.
The prerequisites are deliberately bounded:
- A cleanroom rated Class 10,000 (ISO 8) or higher for sensor-housing assembly
- An ISO 13485 quality management system, or an equivalent
- Basic cleanroom protocol knowledge — full assembly training is provided
Why the component split matters commercially
The way the kit is divided is not arbitrary — it is what makes the numbers work. Because the accuracy-critical parts ship finished and tested, your cleanroom requirement stays limited to final assembly. Because packaging and documentation arrive unbranded, you control the brand and hold the registration. And because the product qualifies as locally finished, it can qualify for local-content and tender programmes that a finished import cannot.
Frequently asked questions
Is the sensor already calibrated when it ships? Yes. The sensor is produced, calibrated and released on the manufacturer's line, with functional screening on every batch. Final assembly does not touch the sensing element.
Do I need engineering staff to assemble a CGM SKD kit? No. Assembly is designed as guided snap-fit operations with SOPs and training. Basic cleanroom protocol knowledge is enough to start.
Can the components be customised? Branding, packaging, manual and app localisation are yours to control. The sensor and transmitter engineering is standardised to protect the accuracy and certification the model depends on.
What if a component fails incoming inspection? Acceptance criteria are defined in writing before the first shipment, and out-of-spec batches are handled through a documented quality process with your partner.
