START YOUR PCB & PCBA REVIEW
Engineering Support Before Production
A project engineer coordinates DFM, process and quality input from file preparation through assembly, inspection and testing. Open questions and proposed changes are returned for your approval before production.
01
PCB Footprint & Layout Mismatches
Footprint and library mismatches can cause assembly defects or production delays even when automated DRC checks pass. DFM findings identify the affected locations and recommended corrections.
02
Component Shortages & Obsolescence
Review incomplete part numbers, availability, lifecycle status and proposed alternatives before components are ordered.
03
Hidden Assembly Defects
SPI, AOI and X-ray inspection are matched to package and solder-joint risks, with acceptance requirements agreed before shipment.
04
Production Readiness
Confirm materials, approved files, test inputs and production requirements before release. Your quotation identifies the schedule and any open dependencies.
Manufacturing scope, inspection coverage and delivery timing are confirmed for your order.
PROOF, NOT PROMISES
DFM Findings Before PCB Assembly
A DFM report example for a 12-layer control board records manufacturability findings with affected locations and recommended corrections. Review the sample report to see how issues are documented before assembly.
ENGINEERING DFM REVIEW
- 01A power MOSFET (LFPAK56) footprint where the pin heel extended 0.08 mm beyond the pad - a latent solder-joint reliability risk on a current-carrying part
- 02A 2512 current-sense resistor footprint with 0.34 mm pad-to-pin mismatch - high tombstoning probability in reflow
- 03Chip components placed 2.5 mm from the board edge against a 3.0 mm process limit - a depanelization stress risk
Request a sample DFM report or send your design files for engineering review.

Questions Engineers Ask Before the First Order
What files do you need for a PCBA quote?
Gerber files (RS-274X or ODB++), a BOM with manufacturer part numbers, and pick-and-place (centroid) data. Assembly drawings and test specifications help but aren't required to start. We quote turnkey, partial-turnkey and consigned builds.
Can you review my files before production?
Yes. Send your available Gerber files, BOM and assembly requirements. The review identifies manufacturing concerns, missing inputs and proposed changes for your confirmation.
What is your minimum order quantity?
Send the required prototype, pilot or production quantity. We will confirm the suitable manufacturing scope and order terms for your project.
How fast can you deliver?
Delivery timing depends on PCB construction, component availability, quantities, testing and approved files. Your quotation confirms the proposed schedule and any expedited options.
Can you source all the components, including hard-to-find parts?
Send your BOM with manufacturer part numbers and sourcing requirements. Availability, lifecycle status, proposed alternatives and verification needs are reviewed before purchasing.
What assembly classes and standards do you build to?
State the workmanship standard and acceptance class required for your project. Certificate copies are available for review; the holder, site and scope relevant to your order must be confirmed.
Can you handle fine-pitch BGA and very small components?
Fine-pitch and small-component assembly requirements are reviewed against the land pattern, stencil strategy, component data, board condition and inspection plan.
How do you protect my design files and IP?
Request an NDA before exchanging confidential files. Access, authorized recipients and project document requirements can then be agreed.
Where are you located, and can I audit the factory?
Manufacturing support is available through China and Vietnam, with a US office for customer communication. Contact us to discuss the proposed manufacturing site and audit arrangements.
What warranty do you offer on assembled boards?
Workmanship warranty coverage, handling of component issues and any return conditions are confirmed in the terms agreed for your order.
