  • 關(guān)于PCB封裝的資料收集整理.pdf

    關(guān)于PCB封裝的資料收集整理. 大的來(lái)說(shuō),元件有插裝和貼裝.零件封裝是指實(shí)際零件焊接到電路板時(shí)所指示的外觀和焊點(diǎn)的位置。是純粹的空間概念.因此不同的元件可共用同一零件封裝,同種元件也可有不同的零件封裝。像電阻,有傳統(tǒng)的針插式,這種元件體積較大,電路板必須鉆孔才能安置元件,完成鉆孔后,插入元件,再過(guò)錫爐或噴錫(也可手焊),成本較高,較新的設(shè)計(jì)都是采用體積小的表面貼片式元件(SMD)這種元件不必鉆孔,用鋼膜將半熔狀錫膏倒入電路板,再把SMD 元件放上,即可焊接在電路板上了。晶體管是我們常用的的元件之一,在DEVICE。LIB庫(kù)中,簡(jiǎn)簡(jiǎn)單單的只有NPN與PNP之分,但實(shí)際上,如果它是NPN的2N3055那它有可能是鐵殼子的TO—3,如果它是NPN的2N3054,則有可能是鐵殼的TO-66或TO-5,而學(xué)用的CS9013,有TO-92A,TO-92B,還有TO-5,TO-46,TO-52等等,千變?nèi)f化。還有一個(gè)就是電阻,在DEVICE 庫(kù)中,它也是簡(jiǎn)單地把它們稱為RES1 和RES2,不管它是100Ω 還是470KΩ都一樣,對(duì)電路板而言,它與歐姆數(shù)根本不相關(guān),完全是按該電阻的功率數(shù)來(lái)決定的我們選用的1/4W 和甚至1/2W 的電阻,都可以用AXIAL0.3 元件封裝,而功率數(shù)大一點(diǎn)的話,可用AXIAL0.4,AXIAL0.5等等。現(xiàn)將常用的元件封裝整理如下:電阻類及無(wú)極性雙端元件:AXIAL0.3-AXIAL1.0無(wú)極性電容:RAD0.1-RAD0.4有極性電容:RB.2/.4-RB.5/1.0二極管:DIODE0.4及DIODE0.7石英晶體振蕩器:XTAL1晶體管、FET、UJT:TO-xxx(TO-3,TO-5)可變電阻(POT1、POT2):VR1-VR5這些常用的元件封裝,大家最好能把它背下來(lái),這些元件封裝,大家可以把它拆分成兩部分來(lái)記如電阻AXIAL0.3 可拆成AXIAL 和0.3,AXIAL 翻譯成中文就是軸狀的,0.3 則是該電阻在印刷電路板上的焊盤間的距離也就是300mil(因?yàn)樵陔姍C(jī)領(lǐng)域里,是以英制單位為主的。同樣的,對(duì)于無(wú)極性的電容,RAD0.1-RAD0.4也是一樣;對(duì)有極性的電容如電解電容,其封裝為RB.2/.4,RB.3/.6 等,其中“.2”為焊盤間距,“.4”為電容圓筒的外徑。對(duì)于晶體管,那就直接看它的外形及功率,大功率的晶體管,就用TO—3,中功率的晶體管,如果是扁平的,就用TO-220,如果是金屬殼的,就用TO-66,小功率的晶體管,就用TO-5,TO-46,TO-92A等都可以,反正它的管腳也長(zhǎng),彎一下也可以。對(duì)于常用的集成IC電路,有DIPxx,就是雙列直插的元件封裝,DIP8就是雙排,每排有4個(gè)引腳,兩排間距離是300mil,焊盤間的距離是100mil。SIPxx 就是單排的封裝。等等。值得我們注意的是晶體管與可變電阻,它們的包裝才是最令人頭痛的,同樣的包裝,其管腳可不一定一樣。例如,對(duì)于TO-92B之類的包裝,通常是1 腳為E(發(fā)射極),而2 腳有可能是B 極(基極),也可能是C(集電極);同樣的,3腳有可能是C,也有可能是B,具體是那個(gè),只有拿到了元件才能確定。因此,電路軟件不敢硬性定義焊盤名稱(管腳名稱),同樣的,場(chǎng)效應(yīng)管,MOS 管也可以用跟晶體管一樣的封裝,它可以通用于三個(gè)引腳的元件。Q1-B,在PCB 里,加載這種網(wǎng)絡(luò)表的時(shí)候,就會(huì)找不到節(jié)點(diǎn)(對(duì)不上)。在可變電阻

  • PCA9549 Octal bus switch with

    The PCA9549 provides eight bits of high speed TTL-compatible bus switching controlledby the I2C-bus. The low ON-state resistance of the switch allows connections to be madewith minimal propagation delay. Any individual A to B channel or combination of channelscan be selected via the I2C-bus, determined by the contents of the programmable Controlregister. When the I2C-bus bit is HIGH (logic 1), the switch is on and data can flow fromPort A to Port B, or vice versa. When the I2C-bus bit is LOW (logic 0), the switch is open,creating a high-impedance state between the two ports, which stops the data flow.An active LOW reset input (RESET) allows the PCA9549 to recover from a situationwhere the I2C-bus is stuck in a LOW state. Pulling the RESET pin LOW resets the I2C-busstate machine and causes all the bits to be open, as does the internal power-on resetfunction.

  • Input Signal Rise and Fall Tim

    All inputs of the C16x family have Schmitt-Trigger input characteristics. These Schmitt-Triggers are intended to always provide proper internal low and high levels, even if anundefined voltage level (between TTL-VIL and TTL-VIH) is externally applied to the pin.The hysteresis of these inputs, however, is very small, and can not be properly used in anapplication to suppress signal noise, and to shape slow rising/falling input transitions.Thus, it must be taken care that rising/falling input signals pass the undefined area of theTTL-specification between VIL and VIH with a sufficient rise/fall time, as generally usualand specified for TTL components (e.g. 74LS series: gates 1V/us, clock inputs 20V/us).The effect of the implemented Schmitt-Trigger is that even if the input signal remains inthe undefined area, well defined low/high levels are generated internally. Note that allinput signals are evaluated at specific sample points (depending on the input and theperipheral function connected to it), at that signal transitions are detected if twoconsecutive samples show different levels. Thus, only the current level of an input signalat these sample points is relevant, that means, the necessary rise/fall times of the inputsignal is only dependant on the sample rate, that is the distance in time between twoconsecutive evaluation time points. If an input signal, for instance, is sampled throughsoftware every 10us, it is irrelevant, which input level would be seen between thesamples. Thus, it would be allowable for the signal to take 10us to pass through theundefined area. Due to the sample rate of 10us, it is assured that only one sample canoccur while the signal is within the undefined area, and no incorrect transition will bedetected. For inputs which are connected to a peripheral function, e.g. capture inputs, thesample rate is determined by the clock cycle of the peripheral unit. In the case of theCAPCOM unit this means a sample rate of 400ns @ 20MHz CPU clock. This requiresinput signals to pass through the undefined area within these 400ns in order to avoidmultiple capture events.For input signals, which do not provide the required rise/fall times, external circuitry mustbe used to shape the signal transitions.In the attached diagram, the effect of the sample rate is shown. The numbers 1 to 5 in thediagram represent possible sample points. Waveform a) shows the result if the inputsignal transition time through the undefined TTL-level area is less than the time distancebetween the sample points (sampling at 1, 2, 3, and 4). Waveform b) can be the result ifthe sampling is performed more than once within the undefined area (sampling at 1, 2, 5,3, and 4).Sample points:1. Evaluation of the signal clearly results in a low level2. Either a low or a high level can be sampled here. If low is sampled, no transition willbe detected. If the sample results in a high level, a transition is detected, and anappropriate action (e.g. capture) might take place.3. Evaluation here clearly results in a high level. If the previous sample 2) had alreadydetected a high, there is no change. If the previous sample 2) showed a low, atransition from low to high is detected now.
