We strive to provide multiple laminate options to ensure a quality product is delivered to our customers. We normally use the laminate thickness as per your specifications and needs. Though, our team offers a standard thickness of 1.6 mm (0.063 inch). Sometimes, the circuit board core thickness and soldermask coating must be considered for trace impedance. When computing impedance, the consequences of conformal coating must be taken into account as the circuit boards are usually covered in soldermask. In general, soldermask decreases the impedance on thin traces. The soldermask has considerably less effect when the trace thickness increases.
我們努力提供多個(gè)層壓選項(xiàng),以確保的優(yōu)質(zhì)產(chǎn)品交付給我們的客戶。我們通常根據(jù)您的規(guī)格和需要使用層壓板厚度。然而,我們的團(tuán)隊(duì)提供了1.6毫米(0.063英寸)的標(biāo)準(zhǔn)厚度。有時(shí),深圳pcb加急打樣的電路板芯厚度和焊錫涂層必須考慮到微量阻抗。

當(dāng)計(jì)算阻抗時(shí),必須考慮保形涂層的后果,因?yàn)?/span>深圳pcb加急打樣電路板通常用焊錫掩模覆蓋。通常,焊錫掩模減小了薄跡線上的阻抗。當(dāng)跟蹤厚度增加時(shí),該焊料掩模具有相當(dāng)小的效果。
