class=\"wp-block-paragraph\">For otherwise comparable boards, increasing thickness generally increases stiffness. Board dimensions, support span, material, layup and loads also affect deflection. A thin rigid board is not automatically a flex circuit; it should not be treated as one simply because it bends.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Layer count does not uniquely determine finished thickness. A different total thickness may require a stackup revision, but it does not by itself determine an impedance change. Impedance depends on the relevant trace geometry, dielectric spacing and materials. Review the proposed construction with the fabricator and use the <a href=\"https:\/\/lead-pcb.com\/ja\/blog\/controlled-impedance-pcb-guide\/\">\u30a4\u30f3\u30d4\u30fc\u30c0\u30f3\u30b9\u5236\u5fa1PCB\u8a2d\u8a08\u30ac\u30a4\u30c9<\/a> for the electrical specification. For material selection, see <a href=\"https:\/\/lead-pcb.com\/ja\/blog\/fr4-pcb-guide\/\">FR-4 PCB materials and design<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Worked Example: Will a 1.6 mm Board Fit a Card-Edge Connector?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A PCB thickness tolerance must be compared with the connector&#8217;s full permitted card range at the same surfaces. The following educational example combines a real connector drawing with a separate supplier&#8217;s published board tolerance. It is not a measured customer design or a qualification result.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Read the connector drawing<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">\u3053\u306e <a href=\"https:\/\/suddendocs.samtec.com\/prints\/htec8-1xxx-xx-x-dv-xx-x-xx-mkt.pdf\">Samtec HTEC8 drawing, revision N<\/a>, retrieved October 29, 2026, gives the <strong>-01 card-thickness option<\/strong> a 1.57 mm nominal mating card with a <strong>\u00b10.157 mm pad-to-pad<\/strong> tolerance. Its calculated limits are:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>1.57 &#8211; 0.157 = 1.413 mm minimum; 1.57 + 0.157 = 1.727 mm maximum.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The series drawing also includes a different card-thickness option. Check the exact connector part, current drawing revision, lead-in and all other mating requirements before using these numbers.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Compare the full board range<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">As a separate supplier example, <a href=\"https:\/\/jlcpcb.com\/capabilities\/pcb-capabilities\/\">JLCPCB&#8217;s capabilities page<\/a>, checked October 29, 2026, lists a \u00b110% thickness tolerance for boards at least 1.0 mm thick. Applying that illustrative tolerance to a <strong>1.60 mm nominal<\/strong> board gives:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>1.60 \u00d7 0.90 = 1.44 mm minimum; 1.60 \u00d7 1.10 = 1.76 mm maximum.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If that board tolerance applied to the same pad-to-pad surfaces at the mating edge, its 1.76 mm upper limit would exceed the connector&#8217;s 1.727 mm upper limit by <strong>0.033 mm<\/strong>. Its 1.44 mm lower limit would be 0.027 mm above the connector&#8217;s minimum. Under that condition, the board tolerance alone would not ensure that the entire permitted board range meets the connector&#8217;s thickness range.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The supplier page does not establish that its thickness tolerance uses those pad-to-pad surfaces. Obtain the measurement definition before comparing the physical requirements. Neither the published values nor this calculation proves that a particular manufactured card passes or fails.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Record a possible specification and open questions<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">One hypothetical request is <strong>1.57 mm \u00b10.10 mm pad-to-pad at the mating edge<\/strong>, giving a range of <strong>1.47 to 1.67 mm<\/strong>. On the same defined surfaces, that requested range sits inside the connector&#8217;s stated range by 0.057 mm at each limit.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th class=\"has-text-align-left\" data-align=\"left\">\u8981\u4ef6<\/th><th class=\"has-text-align-left\" data-align=\"left\">Example range<\/th><th class=\"has-text-align-left\" data-align=\"left\">Status<\/th><\/tr><\/thead><tbody><tr><th class=\"has-text-align-left\" data-align=\"left\">HTEC8 -01 mating card<\/th><td class=\"has-text-align-left\" data-align=\"left\">1.413 to 1.727 mm pad-to-pad<\/td><td class=\"has-text-align-left\" data-align=\"left\">Published connector drawing; verify revision and other requirements.<\/td><\/tr><tr><th class=\"has-text-align-left\" data-align=\"left\">Illustrative 1.60 mm board at \u00b110%<\/th><td class=\"has-text-align-left\" data-align=\"left\">1.44 to 1.76 mm<\/td><td class=\"has-text-align-left\" data-align=\"left\">Published tolerance example; pad-to-pad equivalence unconfirmed.<\/td><\/tr><tr><th class=\"has-text-align-left\" data-align=\"left\">Proposed 1.57 mm board at \u00b10.10 mm<\/th><td class=\"has-text-align-left\" data-align=\"left\">1.47 to 1.67 mm pad-to-pad<\/td><td class=\"has-text-align-left\" data-align=\"left\">Hypothetical request; fabrication and inspection approval pending.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The proposed tolerance is not a published fabricator capability.

many general-purpose rigid boards is 1.6 mm nominal finished thickness, approximately 0.063 inch or 63 mil. JLCPCB&#8217;s standard PCB thickness guide, updated September 9, 2026, describes 1.6 mm as a common standard thickness. Other dimensions are used too, as described in Altium&#8217;s board thickness and stackup guide. A nominal value is a target, not a measurement or an acceptance range. Before selecting one, check the finished board&#8217;s tolerance against the actual connector, enclosure and stackup requirements. What Is the Standard PCB Thickness? A common standard circuit board thickness is 1.6 mm nominal, but that is a convention rather than a mandatory size for every design.
