Advanced packaging & industrialisation
I help technology teams choose viable solutions, uncover manufacturing risks and decide what to do next.
I’m Ossi Lahtinen, founder of Phloem Value. My expertise was built through 13 years of turning a breakthrough in glass laser welding into practical packaging solutions and repeatable production.
The person behind Phloem
We made possible what had been considered impossible: laser welding glass to create hermetic packages for demanding electronics.
I helped turn that breakthrough into a foundation for glass-based hermetic packaging — connecting the technology with customer applications, manufacturing processes and the partners needed to bring it into production.
That experience shapes how I work today: seeing what a technology could enable, understanding what stands in its way, and helping teams turn its potential into practical progress.
Across development, customer collaboration and industrialisation, including at least ten development projects.
A collaborator’s perspective
“Exceptional engineering rigor, strong product-oriented mindset, and ability to translate complex technical challenges into robust, customer-focused solutions.”

When to bring me in
Bring me in when technical choices, manufacturing questions or the work between teams need a clearer way forward.
You have several promising options, but no clear basis for choosing between them.
I compare technology routes against your product requirements, manufacturing constraints and available evidence.
A clear comparison, the critical unknowns and a plan for the tests needed to decide.
The prototype works. The path to reliable, repeatable production is less clear.
I help identify what is missing in the process, testing and supplier chain before you commit to the next stage.
A practical industrialisation plan with priorities, responsibilities and decision points.
The experts and partners are involved, but progress is fragmented.
I work across engineering, manufacturing and external partners to clarify interfaces and resolve questions between teams.
Agreed requirements, clear ownership and coordinated next steps.
Technical expertise
My experience covers glass bonding, electrical connections through glass, wafer-level processing, assembly, reliability testing and production scale-up.
In customer projects, I have worked across implantable medical electronics, MEMS-based sensing and chemical sensing platforms. The recurring task is to connect demanding product requirements with a technical solution that can be manufactured reliably.
Glass laser welding and bonding, through-glass vias (TGV), coatings, structuring and singulation.
Materials, tolerances, electrical interfaces, assembly and interconnects, including wire bonding, flip-chip and BGA.
Hermeticity, reliability, experiments, process windows and equipment qualification (IQ/OQ/PQ).
Yield, traceability, equipment, supplier capabilities and the transition from development to production.

Working together
Each engagement is scoped around your needs, from a focused technical review to ongoing support within your industrialisation programme.
We clarify the challenge, the next decisions and the information already available.
We agree objectives, deliverables, responsibilities and the level of involvement.
I work with your team and partners to resolve questions and turn findings into action.
The Phloem approach
A good solution needs to work technically, deliver value and be practical to produce. The Phloem Lens System helps bring those questions into the same conversation.
What are we trying to achieve?
What do we know, and what still needs testing?
What matters to the customer and the business?
Who and what need to work together?
What should happen next, and in what order?
