Where I can help
Resolve the questions
holding up your build.
Tell me where your project stands. Start a discussion even if the production files are still being prepared.
Files and BOM revisions
Align BOM, Gerber and placement revisions, identify missing details and coordinate questions before production release.
Review project preparationMissing or delayed parts
Clarify sourcing needs, follow availability and bring proposed alternatives to your authorised engineering contact.
Discuss your material planProduction and quality questions
Coordinate incoming-material issues, first-build checks, rework discussions and the records agreed for your project.
Discuss your buildA closer look at assembly
Small components.
Important details.
Bring the details into the discussion: package types, connector orientation, material choices and test coverage.
01
Processor & memory layouts
Package selection, orientation and assembly requirements belong in the released build files.
02
Leaded IC assembly
Lead geometry, handling and inspection requirements should be agreed for each design.
03
Connectors & interfaces
Polarity, mechanical fit and connector orientation need clear assembly notes.
04
Dense surface-mount layouts
Define component placement, material choices and the required inspection coverage.
Board close-ups are illustrative. Process capability and acceptance criteria are confirmed for each project.

How we work together
From first enquiry
to an agreed build.
A straightforward process with a defined owner for open questions at each stage.
Share your project
Send the product requirements, available files, quantities and target date.
Close the gaps
Clarify revisions, sourcing choices and testing needs with suitable partners.
Confirm the scope
Review pricing, lead time, contracting party and responsibilities before ordering.
Track the build
Follow agreed milestones, production questions and delivery documentation.
Quality approach
Know what will
be checked.
Define evidence and acceptance criteria alongside the manufacturing scope. That makes quotations easier to compare and handovers easier to manage.
Inspection methods, partner certifications and process limits are verified for your project. No factory certification is claimed for HEHONG PCBA.
Revision control
Agree the BOM, PCB and placement-file versions used for quotation and production.
Material decisions
Document approved parts, substitutions and customer-supplied material responsibilities.
Test coverage
Specify required inspections, functional checks, fixtures and programming before release.
Delivery records
Agree the reports, labels and packaging to be supplied with the finished build.

A few details
before we start.
Have a project-specific question? Include it in your enquiry.
Ask HehongAre you a factory or an independent coordinator?
HEHONG PCBA is Hehong’s independent sourcing and project coordination service in Shenzhen. Manufacturing is carried out by project-specific partners. The contracting party, manufacturing site and responsibilities are confirmed before you place an order.
Can I start with a prototype or a small batch?
Yes, enquiries for prototypes and small batches are welcome. Feasibility, minimum quantities, setup costs and timing depend on the board, materials and manufacturing partner. These are confirmed in the project quotation.
Can I supply some or all of the components?
You can request customer-supplied material, partial sourcing or broader sourcing support. Please identify supplied items in the BOM and specify quantities, packaging and expected availability.
What if my BOM or Gerber files are not ready?
Start with your product description, quantity, board status and target date. The initial conversation can identify what is missing. A firm manufacturing quotation may need the released production files.
How are testing and quality requirements agreed?
Inspection, functional testing, programming, sampling, acceptance criteria and required reports are defined for each project. Specialist tests, fixtures and certifications must be confirmed with the selected manufacturing partner.
Can we discuss confidentiality before sharing files?
Yes. Ask to agree confidentiality and file-sharing arrangements before sending sensitive designs. This website has no file-upload service; project files are exchanged separately after the recipient and arrangements are confirmed.
