About Excel Circuit

One Partner Across the PCB Lifecycle

PCB programs often lose time when design intent, fabrication capability, component availability, assembly constraints, and test requirements are handled in isolation. Excel Circuit brings those decisions into one coordinated project path.

Our role is to help convert technical requirements into build-ready data, identify issues before they reach production, and maintain practical communication from initial review through delivery.

How We Work

A Practical Five-Step Project Workflow

Clear inputs and early engineering questions help reduce avoidable quotation changes, production holds, and repeat-build risk.

STEP 01

Share Requirements

Provide files, quantities, schedule, application, and acceptance criteria.

STEP 02

Engineering Review

We identify technical questions, missing data, and manufacturability concerns.

STEP 03

Scope & Quote

Materials, processes, test needs, deliverables, and assumptions are clarified.

STEP 04

Build & Verify

Production follows the approved data with planned inspection and testing.

STEP 05

Deliver & Improve

Feedback and build records support delivery and future repeat orders.

Quality & Verification

Quality Planning Starts Before Production

Inspection and testing should match the board technology, application risk, customer specification, and production volume. We review these requirements during quotation so the build plan is clear before release.

Pre-production reviewFiles, materials, tolerances, BOM data, and process requirements.

In-process controlFabrication and assembly checks aligned with the selected build flow.

Inspection and testingVisual, electrical, dimensional, AOI, X-ray, functional, or project-specific verification as applicable.

Build records and feedbackProject information supports traceability and repeat production planning.
