The key is maintaining stable electrical contact and shielding performance under extreme conditions, where factors such as thermal contraction, material compatibility, dimensional changes, compression variation, oxidation, and thermal cycling reliability can affect the entire shielding system.

(BeCu) is widely used in EMI shielding applications because it provides a balance between:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>\u042d\u043b\u0435\u043a\u0442\u0440\u043e\u043f\u0440\u043e\u0432\u043e\u0434\u043d\u043e\u0441\u0442\u044c<\/li>\n\n\n\n<li>\u041c\u0435\u0445\u0430\u043d\u0438\u0447\u0435\u0441\u043a\u0430\u044f \u043f\u0440\u043e\u0447\u043d\u043e\u0441\u0442\u044c<\/li>\n\n\n\n<li>Spring-like recovery characteristics<\/li>\n\n\n\n<li>Long-term contact reliability<\/li>\n<\/ul>\n\n\n\n<p>For EMI shielding structures, electrical conductivity is important because the shielding component must provide a continuous low-impedance electrical path.However, conductivity alone does not determine EMI performance.The actual shielding behavior also depends on:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Contact condition<\/li>\n\n\n\n<li>\u041e\u0431\u0440\u0430\u0431\u043e\u0442\u043a\u0430

Temperature?<\/h3>\n\n\n\n<p>This is an important distinction in low-temperature applications.Suppose a Spiral Tube is installed at 25\u00b0C using the recommended dimensions and achieves the desired compression condition.As the temperature decreases:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The Spiral Tube changes dimension.<\/li>\n\n\n\n<li>The housing changes dimension.<\/li>\n\n\n\n<li>The installation groove changes dimension.<\/li>\n\n\n\n<li>Different materials may experience different amounts of thermal contraction.<\/li>\n<\/ul>\n\n\n\n<p>Therefore:<\/p>\n\n\n\n<p><strong>A 25% compression condition at room temperature does not automatically mean that exactly the same geometric compression condition will be maintained at low temperature.<\/strong>For demanding low-temperature applications, it is therefore useful to evaluate at least three conditions:<\/p>\n\n\n\n<figure

Don&#8217;t Choose a Plating Only Because It Has the Highest Conductivity<\/h3>\n\n\n\n<p>Spiral Tubes may use surface treatments to improve contact performance, environmental resistance, corrosion resistance, or material compatibility.Depending on the product configuration, Handa can provide surface treatments including:<\/p>\n\n\n\n<ul

it would be overly simplistic to say:&#8221;Gold is the best, so gold should always be selected for low-temperature applications.&#8221;<\/p>\n\n\n\n<p>In actual engineering design, the following factors should be considered together:\u201c<strong>Base Material + Plating + Mating Material + Environment + Contact Requirement + Cost<\/strong>\u201d\uff0cFor some applications, the primary purpose of the surface treatment may be to improve resistance to oxidation or maintain stable electrical contact.For other applications, long-term environmental durability may be the more important consideration.Therefore, surface treatment should be evaluated as part of the overall electrical contact system rather than as an isolated parameter.<\/p>\n\n\n\n<hr class=\"wp-block-separator

low-temperature and cryogenic applications, Spiral Tube selection should consider <strong>temperature, material, mechanical structure, and compression<\/strong> together\u2014not just dimensions.Handa offers Spiral Shield solutions with different materials, tube diameters, compression conditions, and surface treatments. Customized designs are also available based on drawings and application requirements.<\/p>\n\n\n\n<p>To recommend a suitable configuration, provide:<strong>Temperature + Housing Material + Groove Size + Spiral Tube OD + EMI Requirement<\/strong>\u3002These parameters help determine the appropriate <strong>material, structure, and compression configuration<\/strong> for your application.<\/p>\n\n\n\n<p><a href=\"https:\/\/www.handashielding.com\/contact-us.html\" title=\"We can provide free samples\">If you still have questions, please contact our engineers.<\/a><\/p>\n\n\n\n<p><\/p>","protected":false},"excerpt":{"rendered":"<p>Introduction For EMI engineers, selecting a Spiral Tube for low temperature applications requires more than choosing a cold-resistant material. The key is maintaining stable electrical contact and shielding performance under extreme conditions, where factors such as thermal contraction, material compatibility, dimensional changes, compression variation, oxidation, and thermal cycling reliability can affect the entire shielding system.
