probes (spring probes) are terminals for inspection equipment mainly used for inspection of various electronic components, semiconductor wafers, IC sockets, printed circuit boards, etc.<br>\nThe contact probe (spring probe) is mainly composed of three parts called a spring, a barrel, and a plunger.<br>\nWhen the inspection of IC sockets is subdivided, there are two types, a test socket that measures electrical characteristics and a burn-in socket that measures reliability such as durability, and the performance required for the plunger differs.<br>\nIn addition, it is necessary to select a suitable tip shape according to the material and shape of the inspection destination.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\"

Spring-loaded Connectors (Pogo Pin Connectors)<\/h2>\n\n\n\n<p>Spring-loaded Connectors (Pogo Pin Connectors) are used for connections between boards, power supply connections, and data communication connections.<br>\nSpring-loaded Connectors (Pogo Pin Connectors) consist of 3 parts: a spring, a barrel, and a plunger.<br>\nRegarding suitable applications, it is used as a connection terminal for camera lenses, batteries, in wearable terminals and for different types of modules. You can also find it as a charging terminal in built-in batteries.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Features of our Plunger products<\/h2>\n\n\n\n<p>We manufacture plungers by our original Cold Heading machines.<br>\nIt is possible to propose mass productivity and cost reduction of plungers suitable for spring connectors and spring probes by increasing the processing speed per product without generating metal scraps by the ultra-fine heading that has been extremely advanced so far. is.<br>\nIn addition, the plating is generally base Ni plating + Au plating. This is because Au plating is optimal because of the application environment where high corrosion resistance, high conductivity, and low contact resistance are required.<br>\nWe manufacture plungers for probes, spring connectors, and pogo pins according to the customer's request, so please feel free to contact us.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Related products<\/h2>\n\n\n\n<p>For related products, please follow the link :<br>Related page\uff1a<\/p>\n\n\n\n<ul>\n<li><a href=\"\/en\/products\/p1105\">Terminals for checking \/ Probe pins \/ Checker pins<\/a><\/li>\n\n\n\n<li><a href=\"\/en\/cold-forging\/\">Cold Heading (Cold Forging, Cold Forming)<\/a><\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Product samples<\/h2>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-3 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<p class=\"has-text-align-center\">Plunger(middle rib type)<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<p class=\"has-text-align-center\">Plunger(shell type)<\/p>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-8 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-vertically-aligned-top is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"http:\/\/133.125.84.183\/wp\/wp-content\/uploads\/2023\/08\/p1118-9.jpg\" alt=\"Plunger(middle rib type)\" class=\"wp-image-8716\"\/><figcaption class=\"wp-element-caption\">Overall view<\/figcaption><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-full is-resized\"><img decoding=\"async\" src=\"http:\/\/133.125.84.183\/wp\/wp-content\/uploads\/2023\/08\/p1118-10.jpg\" alt=\"Plunger(middle rib type)\" class=\"wp-image-8717\" style=\"width:248px;height:155px\" \/><figcaption class=\"wp-element-caption\">Tip concave shape<br>Effective for securing contact with solder balls<\/figcaption><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"http:\/\/133.125.84.183\/wp\/wp-content\/uploads\/2023\/08\/p1118-11.jpg\" alt=\"\u03c60.2mm Plunger(shell type)\" class=\"wp-image-8718\"\/><figcaption class=\"wp-element-caption\">Wire diameter \u03c60.2mm<\/figcaption><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"http:\/\/133.125.84.183\/wp\/wp-content\/uploads\/2023\/08\/p1118-12.jpg\" alt=\"\u03c60.3mm Plunger (shell type)\" class=\"wp-image-8719\"\/><figcaption class=\"wp-element-caption\">Wire diameter \u03c60.3mm<\/figcaption><\/figure>\n<\/div>\n<\/div>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h4 class=\"wp-block-heading\">Please <a href=\"\/en\/inquiry\">contact<\/a> FINECS for details.<\/h4>\n","protected":false},"excerpt":{"rendered":"<p>Please contact FINECS when it comes to the production of plungers for contact probes and spring connectors.<\/p>\n","protected":false},"featured_media":4843,"template":"","meta":{"_lmt_disableupdate":"","_lmt_disable":""},"products-category":[19,13,20,21],"acf":{"shapes_object":""},"_links":{"self":[{"href":"http:\/\/133.125.84.183\/en\/wp-json\/wp\/v2\/products\/416"}],"collection":[{"href":"http:\/\/133.125.84.183\/en\/wp-json\/wp\/v2\/products"}],"about":[{"href":"http:\/\/133.125.84.183\/en\/wp-json\/wp\/v2\/types\/products"}],"version-history":[{"count":30,"href":"http:\/\/133.125.84.183\/en\/wp-json\/wp\/v2\/products\/416\/revisions"}],"predecessor-version":[{"id":5670,"href":"http:\/\/133.125.84.183\/en\/wp-json\/wp\/v2\/products\/416\/revisions\/5670"}],"wp:featuredmedia":[{"embeddable":true,"href":"http:\/\/133.125.84.183\/en\/wp-json\/wp\/v2\/media\/4843"}],"wp:attachment":[{"href":"http:\/\/133.125.84.183\/en\/wp-json\/wp\/v2\/media?parent=416"}],"wp:term":[{"taxonomy":"products-category","embeddable":true,"href":"http:\/\/133.125.84.183\/en\/wp-json\/wp\/v2\/products-category?post=416"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
