一下就是pcb源博自動(dòng)拼板開(kāi)料系統(tǒng)下載資料介紹說(shuō)明: 一、約定術(shù)語(yǔ): 大板(Sheet)(也叫板料):是制造印制電路板的基板材料,也叫覆銅板,有多種規(guī)格。如:1220X1016mm。 拼板(panel)(也叫生產(chǎn)板):由系統(tǒng)根據(jù)拼板設(shè)定的的范圍(拼板最大長(zhǎng)度、最小長(zhǎng)度和拼板最大寬度、最小寬度)自動(dòng)生成; 套板(Unit):有時(shí)是客戶定單的產(chǎn)品尺寸(Width*Height);有時(shí)是由多個(gè)客戶定單的產(chǎn)品尺寸組成(當(dāng)客戶定單的尺寸很小時(shí)即常說(shuō)的連片尺寸)。一個(gè)套板由一個(gè)或多個(gè)單元(Pcs)組成; 單元(Pcs): 客戶定單的產(chǎn)品尺寸。 套板間距(DX、DY)尺寸 :套板在拼板中排列時(shí),兩個(gè)套板之間的間隔。套板長(zhǎng)度與長(zhǎng)度方向之間的間隔叫DX尺寸;套板寬度與寬度方向之間的間隔叫DY尺寸。 拼板工藝邊(DX、DY)尺寸(也叫工作邊或夾板邊):套板與拼板邊緣之間的尺寸。套板長(zhǎng)度方向與拼板邊緣之間的尺寸叫DX工藝邊;套板寬度方向與拼板邊緣之間的尺寸叫DY工藝邊。 單元數(shù)/每套:每個(gè)套板包含有多少個(gè)單元 規(guī)定套板數(shù):在開(kāi)料時(shí)規(guī)定最大拼板包含多少個(gè)套板 套板混排:在一個(gè)拼板里面,允許一部份套板橫排,一部份套板豎排。 開(kāi)料模式:開(kāi)料后,每一種板材都有幾十種開(kāi)料情況,甚至多達(dá)幾百種開(kāi)料情況。怎樣從中選出最優(yōu)的方案?根據(jù)大部份PCB廠的開(kāi)料經(jīng)驗(yàn),我們總結(jié)出了5種開(kāi)料模式:1為單一拼板不混排;2為單一拼板允許混排;3、4、5開(kāi)料模式都是允許二至三種拼板,但其排列的方式和計(jì)算的方法可能不同(從左上角開(kāi)始向右面和下面分、從左到右、從上到下、或兩者結(jié)合)在后面的拼板合并 中有開(kāi)料模式示意圖。其中每一種開(kāi)料模式都選出一種最優(yōu)的方案,所以每一種板材就顯示5種開(kāi)料方案。(選擇的原則是:在允許的拼板種類范圍內(nèi),拼板數(shù)量最少、拼板最大、拼板的種類最少。) 二、 開(kāi)料方式介紹(開(kāi)料方式共有四個(gè)選項(xiàng)): 1、單一拼板:只開(kāi)一種拼板。 2、最多兩種拼板:開(kāi)料時(shí)最多有兩種拼板。 3、允許三種拼板:開(kāi)料時(shí)最多可開(kāi)出三種拼板。(也叫ABC板) 4、使用詳細(xì)算法:該選項(xiàng)主要作用:當(dāng)套板尺寸很小時(shí)(如:50X20),速度會(huì)比較慢,可以采用去掉詳細(xì)算法選項(xiàng),速度就會(huì)比較快且利用率一般都一樣。建議:如產(chǎn)品尺寸小于50mm時(shí),采用套板設(shè)定(即連片開(kāi)料)進(jìn)行開(kāi)料,或去掉使用詳細(xì)算法選項(xiàng)進(jìn)行開(kāi)料。 三、 開(kāi)料方法的選擇 1、常規(guī)開(kāi)料:主要用于產(chǎn)品的尺寸就是套板尺寸,或人為確定了套板尺寸 直接輸入套板尺寸,確定套板間距(DX、DY)尺寸,確定拼板工藝邊(DX、DY)尺寸,選擇生產(chǎn)板材(板料)尺寸,用鼠標(biāo)點(diǎn)擊開(kāi)料(cut)按鈕即可開(kāi)料。 2、套板設(shè)定開(kāi)料(連片開(kāi)料):主要用于產(chǎn)品尺寸較小,由系統(tǒng)自動(dòng)選擇最佳套板尺寸。 套板設(shè)定開(kāi)料 可以根據(jù)套板的參數(shù)選擇不同套板來(lái)開(kāi)料,從而確定那一種套板最好,利用率最高。從而提高板料利用率,又方便生產(chǎn)。

This document provides guidelines for integrating a discrete high speed USB host controller onto a fourlayer desktop motherboard. The material covered can be broken into three main categories: Board design guidelines, EMI/ESD guidelines and front panel USB guidelines. Section 1.1 Background provides an explanation of the routing experiments and testing performed to validate the feasibility of 480 Megabits per second on an actual motherboard. Section 7 contains a design checklist that lists each design recommendation described in this document. High speed USB operation is described in the USB 2.0 Specification (http://www.usb.org/developers/docs.html).
