HDI PCB manufacturing is appropriate when routing density or package escape requires fine features and microvia-based interconnections. The buying decision starts with an agreed stack-up and via structure, not just the term “HDI.” Send the design for a fabrication review before locking the build cost or schedule.
Prototype PCB manufacturing turns a released layout into boards for engineering evaluation. For a useful first build, define what the prototype must prove, keep fabrication and assembly files at the same revision, and agree which checks belong to the bare board and which belong to the assembled circuit.
Standard PCB manufacturing is the practical route for a released FR-4 design that needs a repeatable fabrication specification. Start with the approved board files, layer stack, material requirements and acceptance criteria; then choose bare boards or a complete turnkey assembly.
An SMT solder paste stencil meters paste onto PCB pads before component placement. A useful stencil RFQ includes the paste-layer data, board/panel reference, foil requirements and printer or frame interface. Aperture design must match the component and printing process; copying every copper pad at 1:1 is not a universal rule.
A halogen-free PCB request should identify the required material definition, laminate grade and supporting documentation. A bare-board material claim does not automatically establish the status of every component or the complete assembled product. Define the scope before comparing supplier quotations.
