Engineering review that finds fabrication and assembly risks before they become delays, rework or unnecessary production cost.
Design confidence before production
A design can pass electrical checks and still create fabrication, soldering, inspection or test problems. Our DFM / DFA review combines PCB manufacturing and assembly experience to identify constraints early and recommend practical corrections before files are released.
Focuses on whether the bare PCB can be fabricated reliably, repeatedly and at the intended cost.
Focuses on component placement, soldering, inspection, test access and assembly yield.
Review coverage
Outline, cutouts, slots, edge clearance, tooling features and mechanical constraints reviewed.
In an HDI and fine-pitch BGA project, hole sizes, aspect ratios, microvias, via-in-pad, copper fill and BGA fanout design constraints are checked against process capability.
Fine features, copper distribution, reference planes and controlled-impedance requirements assessed.
Pad geometry, solder-mask openings, courtyard clearance and package compatibility examined.
Placement access, component orientation, thermal mass and soldering sequence reviewed for yield.
AOI visibility, X-ray needs, test-point coverage and programming access considered before build.

Frequently asked questions
Please provide Gerber or ODB++ data, drill files, stackup, fabrication drawings, BOM, pick-and-place data and assembly drawings. Schematics and 3D mechanical files are helpful for a deeper review.
The best time is before final release and purchase commitment. An early layout verification checklist can also be completed during layout so major constraints are addressed before routing is finished.
Yes. We can review against your nominated supplier’s capabilities or general industry rules, provided their specific manufacturing constraints are available.
Send your design package for an engineering review focused on manufacturability, assembly yield and practical cost control.

Practical answers about files, schedule, engineering support, production coordination and confidentiality.
Lead time depends on design maturity, complexity, quantity, material or component availability, testing scope, and how quickly engineering questions are resolved. We confirm the schedule after reviewing your files; urgent prototype or quick-turn options can be discussed where the required process and materials permit.
Gerber and ODB++ are the preferred neutral production formats. If your source data is in a native EDA tool, tell us the software and version; we will confirm compatibility or ask for a controlled Gerber/ODB++ export, drill data, drawings and other release files.
Yes. We can work from an existing design, production package or previous revision. We first check completeness, revision control and the requested scope, then identify any missing data, manufacturability risks or changes that need your approval before work begins.
Project files are limited to personnel and qualified partners who need them for quotation and delivery. Excel Circuit uses reasonable technical and organizational safeguards, does not publish customer designs without permission, and can work under a mutually agreed NDA. Your signed NDA or project agreement controls where it provides specific protections.
Final scope, price and lead time are confirmed after engineering review of your current files and requirements.
