Client Name : A Series A connected-device startup

The Challenge

Ahead of its first hardware launch, the team was managing four separate vendors — one for the enclosure, one for PCB assembly, one for wire harnesses, and one for final assembly — across three time zones. Every design change had to be communicated to each vendor individually, and a tolerance mismatch between the enclosure and the board wasn't caught until final assembly, forcing a costly rework cycle just weeks before launch.

The Approach

Manrulan consolidated all four functions into a single engagement. Our mechanical and electronics teams reviewed the enclosure and PCB designs together from the outset, catching a connector clearance issue during design review instead of at final assembly. Tooling for the enclosure and SMT setup for the board ran in parallel under one project timeline, with a single account team coordinating both.

The Outcome

1. Vendor count reduced from 4 to 1
2. Time-to-first-unit shortened by an estimated 30–40%
3. Zero enclosure-to-board fit issues at final assembly, versus one full rework cycle in the prior process

Client Name : A medical device component manufacturer

The Challenge

The client's product required strict lot traceability across both its machined housing and its internal PCB assembly — a requirement that had previously meant reconciling two separate traceability systems from two separate vendors, with manual cross-referencing to tie a finished unit back to its component lots during audits.

The Approach

Manrulan applied a single traceability framework across both the mechanical and electronic sub-assemblies, tracking component lots, machining batches, and assembly records under one system from raw material intake through final inspection. Tolerance specifications for the housing were validated against the board's mounting and connector requirements during initial design review, rather than reconciled after the fact.

The Outcome

1. Single unified traceability record per finished unit, eliminating manual cross-referencing between vendor systems
2. Tolerance-related fit issues reduced to near zero across production runs
3. Audit preparation time reduced by an estimated 50%

Client Name : A Tier 1 automotive components supplier

The Challenge

After validating a new component design through prototyping with one vendor, the client anticipated the usual disruption of re-qualifying a new manufacturing partner to move into volume production — a process that typically added months of re-testing, re-validation, and renegotiation with their original supplier unable to scale.

The Approach

Because Manrulan managed the project from initial prototyping onward, the transition to volume production reused the same validated tooling design, the same quality baseline, and the same engineering team — with a structured pilot run bridging prototype and full-scale output to confirm manufacturability at volume before committing to final production tooling.

The Outcome

1. Zero vendor re-qualification cycles between prototype and volume production
2. Time-to-volume-production shortened by an estimated 8–12 weeks compared to a vendor-switch scenario
3. Consistent tolerance performance maintained from pilot run through full-scale output

Client Name : A telecom hardware OEM

The Challenge

The client's high-density board design was experiencing a recurring PCBA defect rate at their previous assembly partner, largely traced back to fine-pitch component placement issues and thermal stress from the board's enclosure fit — a problem that fell into a gap between their electronics vendor and their enclosure supplier, with neither taking ownership of the root cause.

The Approach

Manrulan's EMS and mechanical teams reviewed the board layout and enclosure design together, identifying a thermal path conflict between a high-density component cluster and the enclosure's internal geometry. Assembly parameters were adjusted for the fine-pitch components, and enclosure clearances were revised to resolve the thermal stress — addressed as one integrated fix rather than two separate vendor investigations.

The Outcome

1. PCBA defect rate reduced by an estimated 60–70% following the integrated design revision
2. Root cause identified and resolved in a single design review cycle, versus multiple inconclusive investigations with the prior vendor split
3. No recurrence of the defect pattern across subsequent production runs

Client Name : A consumer electronics brand

The Challenge

With a fixed retail launch date, the client's product development timeline had no room for the sequential handoffs typical of a split-vendor model — mechanical tooling completed, then handed to an electronics vendor, then handed again for final assembly — a process that would have pushed their launch past the target retail window.

The Approach

Manrulan ran mechanical tooling (injection molding for the enclosure) and SMT assembly for the PCB in parallel from the start of the production phase, coordinated under a single project timeline. Final box-build assembly began as soon as both components were ready, rather than waiting for a sequential vendor-to-vendor handoff.

The Outcome

1. Overall production timeline compressed by an estimated 25–35% compared to a sequential multi-vendor process
2. Retail launch date met without schedule compression trade-offs on quality inspection steps
3. Single coordinated ramp-up to full production volume post-launch
