PCB Terminal Progressive Stamping: Drawing, Plating and Inspection RFQ Guide
Direct answer: a useful PCB-terminal RFQ should define the terminal geometry, PCB interface, 0.5 mm phosphor-bronze requirement, gold, silver or nickel finish, functional contact zones, critical dimensions, burr direction, inspection scope, quantity and delivery need before progressive-die tooling is released.
This page uses an actual family of stamped PCB terminals manufactured or supplied by Zhengna Technology. The confirmed family uses 0.5 mm phosphor bronze, progressive-die stamping and forming, and gold-, silver- or nickel-plated finishes. The photograph does not establish the exact dimensions, tolerance, plating thickness, electrical rating or inspection result of an individual part.
Confirmed Product Evidence and RFQ-Controlled Requirements
| Item | Confirmed for this family | Still defined by the buyer |
|---|---|---|
| Use | PCB connection terminals | Board location, mating interface, current path and assembly method |
| Material | 0.5 mm phosphor bronze | Exact grade, temper and material documentation |
| Process | Progressive-die stamping and forming | Strip layout, datum plan, bend radii and tooling acceptance |
| Finish | Gold, silver or nickel electroplating within the family | Layer sequence, thickness, zones, masking and acceptance evidence |
| Inspection | Dimensions, hole diameter, flatness and appearance | Critical features, tolerance, equipment, frequency, records and release rule |
| Commercial terms | Starting quantity of one piece, 30-day lead time and pallet packaging | Final quantity, schedule, tooling status and destination-specific packaging |
Start With the PCB Interface
A terminal should not be specified from a catalogue picture alone. Mark the soldering, insertion, spring-contact, fastening or grounding interface on the drawing. Identify which surface carries current, which feature locates the part on the board, which bends establish contact height, and which edges must face away from wires, operators or mating components.
The same visible shape can behave differently when temper, grain direction, bend radius, plating zone or mating force changes. Zhengna Technology therefore reviews the released drawing and interface conditions before confirming tooling or production scope.
Define Phosphor Bronze Beyond Thickness
The confirmed strip thickness for this photographed family is 0.5 mm phosphor bronze. The RFQ should still state the exact grade and temper. Those details affect forming strain, spring recovery, fatigue behaviour and dimensional stability. This page does not convert the material description into a universal spring force, cycle life or electrical rating.
Gold, Silver and Nickel Plating Need Separate Drawing Control
The supplied family includes gold-, silver- or nickel-plated configurations. These are finish choices within the family, not a statement that each part carries all three finishes simultaneously. The drawing should identify the base material, underplate where applicable, finish thickness, local or overall coverage, functional contact zones, masked areas and required evidence.
A finish name alone does not prove solderability, contact resistance, corrosion life, signal performance or automotive qualification. If those outcomes matter, the responsible project specification must name the test method and acceptance criteria.
Progressive-Die Features to Review Before Tooling
- strip direction, carrier position and part orientation;
- pierced holes, slots and the relationship to forming datums;
- bend radii, formed height and spring-arm geometry where applicable;
- burr direction on contact, soldering and assembly edges;
- plating-before-forming versus plating-after-forming responsibility;
- critical dimensions that require first-piece, in-process or final evidence; and
- packaging orientation that prevents tangling, deformation or finish damage.
Inspection Evidence Must Name the Feature
For this family, the confirmed checks cover dimensions, hole diameter, flatness and appearance. The inspection plan should connect each critical feature to its measurement method, sample size, frequency, acceptance limit and retained record. No functional or electrical-performance test has been confirmed for this family, so such testing must not be assumed.
Quotation Inputs
Provide a controlled CAD drawing with dimensions, hole and slot locations, tolerances, material grade and temper, finish requirements, purchase quantity and required timing. If no controlled drawing exists, Zhengna Technology can review a physical sample for measurement, but the parties must confirm nominal dimensions, tolerance authority, interface details and revision control before production release.
For the broader product family, review custom stamped electrical terminals and custom stamping parts. To request a technical quotation review, contact Zhengna Technology.
Frequently Asked Questions
Is 0.5 mm phosphor bronze confirmed?
Yes, for the photographed PCB-terminal family. The exact phosphor-bronze grade and temper still need to be stated in the drawing or quotation specification.
Does every terminal use gold, silver and nickel together?
No. The confirmed family includes gold-, silver- or nickel-plated configurations. The final finish, layer sequence, thickness and zones are controlled by the released drawing.
What inspections are confirmed?
Dimensions, hole diameter, flatness and appearance are confirmed inspection items. Equipment, frequency, numerical results and lot-acceptance status have not been supplied.
Can Zhengna Technology quote from a sample?
Yes. A sample can support measurement and feasibility review, but dimensions, tolerances, interfaces, finish and revision authority must be agreed before production.
