Responsum directum: Zhengna Technology suppedit terminalia electrica et contactus batteriarum ad mensuram, pro conductione in circuitibus impressis (PCB), pro interfacebus replectionis et evacuationis batteriarum, et pro contactibus interruptorum aut butonum. Materialis, temperatio, spissitudo, zonae placationis, directio marginum ac documenta inspectionis conveniuntur secundum schemata edita antequam productio incipiat.
Schema contactus debet separatim indicare substratum, temperationem et finitionem antequam ferramenta edantur. Imago in hac pagina ostendit geometricas formas typicas contactuum. Non autem indicat substratum, temperationem, stratificatio placationis, valorem electricum aut resultatum inspectionis pro quolibet partu depicto.
Incipe ab officio electrico et mechanico
A buyer should not select a contact alloy from colour or a generic catalogue label. First define whether the part is a fixed conductive tab, a spring contact arm, a solder terminal, a grounding finger or a repeated-mating interface. That decision changes the balance among conductivity, spring recovery, fatigue resistance, forming strain, finish compatibility and cost.
For the supplied product family, typical strip thickness is 0.2–2.0 mm. The final thickness is not a current-rating claim: it must be checked with the interface geometry, allowable temperature rise, contact area, mating force and the responsible electrical design.
Material and temper options
| Familia Materialis | Typical grades and conditions | Best-fit buyer use | Important boundary |
|---|---|---|---|
| ETP copper | C11000 / C1100 / T2; commonly half hard or H04, with O temper only where a suitable deep-draw route is confirmed | Fixed conductive tabs, PCB grounding tabs, bus bridges and battery welding tabs without a spring-arm requirement | Approximately 100% IACS conductivity does not deliver the spring recovery expected from a contact arm. |
| Aes signinum | C5191 / C51000 / QSn6.5-0.1 in half-hard, H or EH temper; C5210 / C52100 / QSn8-0.3 in H, EH or SH temper where higher spring force is required | Board-to-board contact arms, battery spring contacts, SIM contacts, button contacts and relay contact springs | C5191-family conductivity is typically about 13–18% IACS. Fatigue, force and insertion-cycle requirements still require project-specific validation. |
| Aes | C2680 / C26000 / H65 in half-hard, H or EH temper; C2720 or C2801 only after drawing review | Cost-sensitive battery-holder contacts, solder terminals, shielding springs and enclosure contacts | Typical conductivity is about 27–28% IACS. Brass is not automatically the optimal choice for a high-cycle spring arm. |
| Higher-performance copper alloys | C17200 / QBe2, C7025 / Cu-Ni-Si, C19400 or C14415, subject to material and compliance review | Projects that combine higher spring strength, fatigue resistance, temperature resistance or conductivity demands | Conductivitas familiae C7025 est typice circa 35–45 % IACS; C19400/C14415 potest esse circa 55–95 % IACS. Proprietates exactae dependent a gradu, temperamento et registris supplicantis. |
| Accipiter inox SUS301 | Dura ad quartam partem per H, ubi designatio contactus permittit | Molae scutantes aut digiti terrae cum conductivitas massiva non est principale criterium electionis | Ne describas SUS301 ut substratum contactus cupri. Functio electrica pendet ex geometria confirmata, interfacie coniungente et finitione. |
Plating debet convenire interfaciem
Plating stanni in typico intervallo 1–5 micrometrorum est optio pretii moderati pro interfacibus soldabilibus, inter quas sunt projecta apta ad soldationem undulatam. Stratum typicum nicielii 2–3 micrometrorum cum tenui, definitione trahendi aureo finitione potest recenseri pro interfacibus resistentiae contactus minoris vel altius frequentialis.
The drawing must specify which faces are functional contact zones, solder zones, masked zones, and cosmetic zones. It must also indicate plating thickness, base layer, local or overall application, adhesion and thickness test requirements, and any soldering or mating validation assigned to the project. A finish name alone does not demonstrate solderability, contact resistance, corrosion life, or signal performance.
Stamping, forming, and burr control
The manufacturing review includes strip layout, grain direction where applicable, blanking and piercing, bend radii, formed height, contact-arm geometry, burr direction, and the relationship between datum features and the mating interface. Tooling and process route depend on the released geometry and volume; this page does not guarantee one universal die type for every contact.
Typical geometric tolerances for this product family may fall within ±0.02–0.05 mm, while a typical burr-height requirement may be ≤0.03 mm. Those values are capability ranges for drawing review, not automatic acceptance limits for every feature. The drawing must identify critical-to-function dimensions, measurement datums and the surfaces where burr direction matters.
Inspection evidence for an OEM order
Critical profile, position, formed height and selected geometric features can be checked with 2D vision measurement or a coordinate measuring machine. The inspection plan should name the equipment, feature, frequency, sample size and acceptance rule. Visual appearance or equipment ownership is not a lot-release result.
- Confirm material grade, temper and thickness against the released specification.
- Identify critical dimensions, datum logic and mating-interface features.
- Define burr direction and maximum height on functional edges.
- Stare zonarum plationis, ordinis stratorum, crassitudinis et probationis necessariae.
- Convenire frequentionem inspectionis primae partis, inspectionis in cursu processus, inspectionis per exempla aut inspectionis finalis pro ordine.
MOQ, tempus ducens et impachatio.
Ordo consuetudinarius ad mensuram incipit ab 1 000 partibus, cum tempore ducente typico 10–15 dierum post confirmationem technicam et commercialem. Programmata confirmata pendet a statu instrumentorum, abilitate materiae, via finitionis, ambitu inspectionis et quantitate ordinis. Impachatio consuetudinaria utitur sacculis internis antistaticis et cartonibus externis, nisi descriptio aut periculum tractationis exigat impachationem separatim convenitam.

Provide the released drawing or model, material and temper, thickness, plating zones, quantity, critical dimensions, burr requirements, mating interface, soldering process where applicable, inspection plan and packaging needs.
How are critical dimensions and burrs checked?
2D vision measurement or a coordinate measuring machine can be used according to the feature and inspection plan. Typical ranges do not replace the released drawing or order-specific acceptance record.
