An extensive range of finished PCB thicknesses can be accomplished with the combination of different core thicknesses and sheets of prepreg. However, the variety of laminate thickness options offered to our customers are range from 0.008 inches to 0.240 inches and they include 0.2 mm (0.0079 inch), 0.4 mm (0.016 inch), 0.5 mm (0.020 inch), 0.6 mm (0.024 inch), 0.8 mm (0.032 inch), 1.0 mm (0.04 inch), 1.2 mm (0.047 inch), 1.5 mm (0.062 inch), 1.6 mm (0.063 inch), 2.0 mm (0.079 inch), 2.3 mm (0.091 inch), etc.

深圳pcb加急打樣的pcb厚度的廣泛范圍可以通過不同芯層厚度和預(yù)浸料片的組合來實現(xiàn)。然而,提供給我們客戶的層壓厚度選項的范圍從0.008英寸到0.240英寸,它們包括0.2毫米(0.0079英寸)、0.4毫米(0.016英寸)、0.5毫米(0.020英寸)、0.6毫米(0.024英寸)、0.8毫米(0.032英寸)、0.032 mm(英寸)、Y mm(英寸)、μmm(I i)。NCH),1.6毫米(0.063英寸),2毫米(0.079英寸),2.3毫米(0.091英寸)等。

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.

我們努力提供多個層壓選項,以確保優(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,我們的團隊提供了1.6毫米(0.063英寸)的標準厚度。有時,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)計算阻抗時,必須考慮保形涂層的后果,因為深圳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,該焊料掩模具有相當(dāng)小的效果。
