Controlled integration route
Six Control Processes from File Review to Shipment
Incoming Material and Subassembly Inspection
Confirm supplied parts, enclosure condition, cable identity and controlled subassemblies.
Mechanical Integration
Release routing, fastening, thermal interfaces, adhesives, torque and work sequence.
Firmware & Configuration
Load the approved revision, verify identity and record configuration where required.
Test & Inspection
Run agreed unit-level functions and inspect mechanics, labels, accessories and cosmetics.
Serialization, Packaging, and Shipment Release
Link the unit record, complete final inspection and release the approved pack-out route.
Mechanical and process controls
Mechanical and Process Details to Confirm Before Final Assembly
Harness Routing
Connector keying, pin map, bend radius, retention, strain relief, label direction and interference checks are released from the approved harness package.
Torque and Fastener Control
Critical fasteners can be controlled by value, sequence, tool, thread-locking method and record requirement defined by the customer.
Thermal Interfaces
Heat sinks, pads, compounds, pressure surfaces and enclosure contact are checked against the mechanical drawing and work instruction.
Conformal Coating and Keep-Out Areas
Material, masking, coverage, cure, inspection and rework rules are agreed before the coating route is released.
Cleanroom Handling
Supported programs can use the published ISO 7 route after the applicable assembly stage and cleanliness evidence are confirmed.
Acceptance Standard
IPC-A-610, IPC/WHMA-A-620, IPC-CC-830 and customer drawings are applied only in the version, class and scope stated in the quotation.

PCBA Inspection and Finished-Unit Testing
The quotation defines the inspection and test scope for the PCBA. Finished-unit functional testing is confirmed separately based on the product specifications and customer test requirements.
Board-level controlAOI, X-ray, ICT, flying probe or PCBA functional checks are selected from board risk and test access.
Finished-unit FCTPower-up, interface, communication, sensor, load, indicator and safety functions are released from the customer test specification.
Fixture controlDesign input, ownership, software, calibration, maintenance, spare parts and change control are agreed before production.
Failure & retestFailure codes, isolation, rework authority, retest rules and final disposition are part of the approved test route.
Final inspectionMechanical fit, cosmetics, labels, accessories, packaging and shipment release are checked independently of electrical pass status.
Unit-level traceability
Trace Every Finished Unit from Materials to Shipment
When included in the quotation, a laser-marked 2D code can connect each finished unit to the material, firmware, test, inspection and shipment records required by the program.

Box build capability FAQ
Questions Engineering, Procurement and Quality Teams Ask
These answers define the review process without turning file-dependent conditions into blanket promises.
What should I send for a box build capability review?
Send the available BOM, PCBA data, mechanical drawings, cable or harness drawings, firmware requirements, test criteria, labeling, packaging requirements and target quantities. EBest PCBA can identify missing inputs during the first review.
Can EBest PCBA link firmware versions and unit-level test results to each serial number?
Yes, when this traceability is included in the approved production process. Firmware, configuration, calibration, functional-test and final-inspection records can then be linked to a unit identifier.
Does EBest PCBA support functional test fixtures?
Yes. Fixture development and functional testing can be included after test access, limits, software, ownership, maintenance and release evidence are confirmed during quotation.
Can EBest PCBA provide cleanroom box build assembly?
Yes, for supported programs subject to process review. Published capability includes a 100 m² ISO 7 (Class 10,000) cleanroom route; product requirements and the applicable assembly stage are confirmed from the project files.
How are box build revisions controlled?
The approved BOM, drawings, firmware, work instructions, test limits and packaging requirements form the released baseline. Changes are reviewed for scope, schedule and cost before revised work proceeds.
Can I request an NDA before sending files?
Yes. Request the NDA first, then send controlled drawings, BOMs, firmware notes or test requirements through the agreed communication route.
