Solving the OSAT Talent Gap in India

India does not have a shortage of engineers. It has a shortage of a narrow set of profiles with hands-on assembly and test experience, concentrated in a handful of disciplines, needed in shift-deep numbers, at several sites at once. That distinction matters because it rules out the obvious answer. Hiring harder in a general engineering market does not produce a process engineer who recognises a delamination signature or a technician who has maintained a specific wire bonder through a production year.

The recurring shortage list is short and consistent. Process engineers who own yield through a ramp rather than only sustain a stable line. Test engineers who can develop and debug programs against a demanding customer specification. Quality and reliability engineers who can carry a qualification. Equipment technicians with genuine tool-level depth across the installed base. MES, automation and manufacturing-data specialists who keep traceability and factory data trustworthy.

Two structural factors sharpen it. Assembly and test runs continuously, so every critical role needs several people to be covered across shifts and absence. And when multiple sites commission in the same window, they compete for the same small experienced pool, which raises both cost and attrition risk at exactly the moment stability matters most.

The first response is to build the talent rather than only search for it. This is a different activity from recruitment. It starts from the role specifications the line actually needs, works backwards to the adjacent profiles that can realistically reach those specifications — electronics and electrical engineering graduates, technicians from precision manufacturing, quality and metrology backgrounds from other high-discipline industries — and then runs a structured process that closes the distance.

In practice that process has four parts. Assessment that filters for aptitude and temperament rather than only credentials, because back-end work rewards systematic diagnosis and discipline under production pressure. Training that is specific to the tool sets, materials and failure modes the site will encounter, not generic semiconductor theory. Mentoring by experienced engineers during the first production exposure, which is where most of the real learning happens. And retention design, because a pipeline that produces excellent people for a competitor two years later has solved someone else's problem.

The advantage of this approach is supply that scales and stays. The cost is lead time: a build pipeline is measured in months, which is why it has to start before facility completion rather than after commissioning reveals the shortfall. Operators who begin this work alongside equipment ordering consistently have a smoother ramp than those who begin it alongside hiring requisitions.

Building a pipeline answers the medium term. It does not answer the first qualification date. For that, the fastest credible route is to bring in people who have already run assembly and test operations, and the natural catchment is Southeast Asia. Malaysia, the Philippines and Singapore have mature semiconductor and electronics workforces built over decades of back-end operations, with exactly the process, test, quality and equipment depth new Indian sites need.

Mobilisation works best when it is designed as a defined-duration capability transfer rather than an open-ended staffing arrangement. Experienced engineers anchor the critical shifts, lead the first qualification cycles, and — crucially — mentor the locally built pipeline while they do it. The tacit knowledge that never makes it into a work instruction transfers through that pairing. As local capability matures, the mobilised layer thins by design instead of by surprise.

The reason this is harder than it sounds is the practical layer beneath it. Work authorisation and documentation, relocation logistics, family considerations, payroll and tax treatment, cross-border compliance and ongoing duty-of-care all have lead times and failure modes. A mobilisation plan that is strong on sourcing and weak on this layer produces offers that do not convert and start dates that move. Handling it as a managed workstream, mapped to the qualification calendar, is what makes the approach reliable.

Used alone, each approach has a predictable failure mode. A build-only strategy is sound but slow, and it asks people with limited production exposure to carry the first customer qualification, which is exactly the wrong moment to be learning. A mobilisation-only strategy covers the early ramp but creates a permanent dependency: costs stay elevated, local capability never deepens, and the site remains exposed if mobilised staff rotate out.

Combined, they answer different parts of the same timeline. Mobilised experience covers the qualification window and sets the operating standard. The build pipeline supplies the sustained, shift-deep bench underneath it. The handover between the two is the actual design problem, and it should be planned explicitly: which roles transition when, what competence evidence triggers the transition, and who owns the mentoring relationship in the meantime.

This is the model AX3 runs for OSAT and assembly and test operations, described in full on the semiconductor and OSAT page: talent manufacturing to build the pipelines, Southeast Asia mobilisation to cover the experience gap now, and the mobility and compliance layer that makes the second one practical. Remote software, data and engineering delivery from India sits alongside both, supporting MES, analytics and integration work so on-site engineering stays focused on the process.

Start from the qualification date and the tool list, and derive role demand by shift for every critical function. Separate roles that must be experienced on day one from roles that can be built, and be honest about which is which — over-optimism here is the most common cause of a ramp that stalls two months before qualification.

Then set lead times per route. Mobilisation lead time is dominated by authorisation and relocation. Build lead time is dominated by training and supervised production exposure. Local experienced hiring is fastest but has the smallest available pool and the highest competitive risk. Sequencing the three against the milestone calendar produces a workforce plan that can actually be tracked, with visible early-warning indicators rather than a single headcount number.

Finally, run retention as part of the plan rather than as a reaction. Clear progression from technician to engineer, visible skill certification, shift patterns that people can sustain, and mentoring relationships that outlast the ramp all cost less than replacing a qualified process engineer in a competitive market.

This article sits alongside two companions: an overview of the OSAT opportunity in India and what is driving the capacity buildout, and a practical read of the India Semiconductor Mission and production-linked incentive schemes for operators and investors. Together they describe the opportunity, the economics and the execution constraint.

If you are planning an assembly and test ramp and want to pressure-test the workforce side of it, the AX3 semiconductor and OSAT page sets out the capability, and a conversation is the quickest way to see whether it fits your milestone calendar.
