印刷電路板設計的主要步驟;



1


:繪製原理圖。



2


:元件庫的創建。



3


:建立原理圖與印製板上元件的網路連接關係。



4


:佈線和佈局。


< br>5


:創建印製板生産使用資料和貼裝生産使用資料。




印製電路板的設計過程中要考慮以下問題:



1




要確保 電路原理圖元件圖形與實物相一致和電路原理圖中網路連接的正確性。



2




印製電 路板的設計不僅僅是考慮原理圖的網路連接關係,而且要考慮電路工程








的一些要求,


電路工程的要求主要是 電源線、地線和其他一些導線的寬度,線路的連接,一些元件的高頻特性,


元件的阻抗、 抗幹擾等。



3




印製電 路板整機系統安裝的要求,主要考慮安裝孔、插頭、定位孔、基準點等



都要滿足要求,各種元件的擺放位置和準確地安裝在規定的位置,同時要便於安裝、系

< br>統調試、以及通風散熱。



4




印製電 路板的可製造性上和它的工藝性上的要求,要熟悉設計規範和滿足生産



工藝要求,使設計出的印製電路板能順利地進行生産。



5




在考慮 元器件在生産上便於安裝、調試、返修,同時印製電路板上的圖形、焊



盤、過孔等要標準,確保元器件之間不會碰撞,又方便地安裝。



6




設計出 印製電路板的目的主要是應用,因此我們要考慮它的實用性和可靠性,



同時減少印製電路板的板層和麵積,從而來降低成本,適當大一些的焊盤、通孔、走線等有利於可


靠性的提高,減少過孔,優化走線,使其疏密均勻,一致性好,使板面的整體佈局美觀一些。< /p>




一、要使所設計的電路板達到預期的 目的,印刷電路板的整體佈局、元器件的擺放位置起著關鍵作用,它直


接影響到整個印刷 電路板的安裝、可靠性、通風散熱、佈線的直通率。



印刷電路 板的外層尺寸優先考慮,


PCB


尺寸過大時,印製線條長,阻抗 增加,抗雜訊能力下降,成本也


增加,過小,則散熱不好,且鄰近線條易受幹擾,因此, 首先對


PCB


的大小和外形,給出一個合理的定位。

< p>
再確定特殊元件的位置和單元電路等,要按電路的流程把整個電路分爲幾個單元電路或模組,並以每 個單元


電路的核心元件(如積體電路)爲中心,其他的元件要按一定的順序均勻、整齊緊 湊地排列在


PCB


板上,但


不要太靠近 這些大的元件,要有一定的距離,特別一些比較大、比較高的元件周圍要保持一定的距離,這樣

< br>有助於焊接和返修。對於功率較大的積體電路要考慮彩散熱片,要給它留有足夠的空間,並且放於印製板的


通風散熱好的位置。同時也不要過於集中,幾個大的元件在同一板子上,要有一定距離, 並且要使他們在


45


角的方向上,稍小的一些積體電路如(


SOP


)要沿軸向排列,電阻容元件則垂直軸向排列,所有這些方向 都


相對


PCB


的生産過程的傳送方向。 這樣使元器件有規律的排列,從而減少在焊接中産生的缺陷。做顯示用的


發光二極體等, 因在應用過程中要用來觀察,應該考慮放於印製板的邊緣處。



一些開關、微調元件等應該放在易於操作的地方。在同頻電路中應考慮元器件之間的分佈參數,一般高

< p>
頻電路中應考慮元器件之間的分佈參數,


一般電路盡可能使元器件平行排列 ,這樣不但美觀,而且易於裝焊,


同時易於批生産,位於電路板邊緣的元器件,距離邊緣 一定要有


3-5


釐米的距離。在考慮元件位置的同時要



PCB


板的熱膨脹係數、

導熱係數、


耐熱性以及彎曲強度等性能進行全面考慮,


以免 在生産中對元件或


PCB


産生不良影響。



PCB


上的元件位置和外形確定後,再考慮


PCB


的佈線。



有了元件的 位置,根據元件位置進行佈線,印製板上的走線盡可能短是一個原則。走線短,佔用通道和


麵積都小,這樣直通率會高一些。在


PCB


板上的輸入端和輸 出端的導線應儘量避開相鄰平行,最好在二線間

放有地線。以免發生電路反饋藕合。印製板如果爲多層板,每個層的信號線走線方向與相鄰板層 的走線方向


要不同。對於一些重要的信號線應和線路設計人員達成一致意見,特別差分信 號線,應該成對地走線,盡力


使它們平行、靠近一些,並且長短相差不大。


PCB


板上所有元件儘量減少和縮短元器件之間的引線和連接,


PCB


板中的導線最小寬度主要由導線與絕緣層基板間的粘附強度和流過它們 的電流值決定。當銅箔厚度爲


0.05mm


,寬度爲

< p>
1-1.5mm


時,通過


2A

的電流,溫度不會高於


3


度。導線寬度

1.5mm


時可滿足要求,對於積


體電路,尤其是數位電路 ,通常選用


0.02-0.03mm


。當然,只要允許,我們盡 可能的用寬線,特別是


PCB



上的電 源線和地線,導線的最小間距主要是由最不壞情況下的線間絕緣電阻和擊穿電壓決定。對於一些積體


電路



IC



以工藝角度考慮可使間距小於


5-8mm


。印製導線 的彎曲處一般用圓弧最小,


避免使用小於


90

< br>度彎


的走線。而直角和夾角在高頻電路中會影響電性能,總之,印製板的佈線要均 勻,疏密適當,一致性好。電


路中儘量避開使用大面積銅箔,否則,在使用過程中時間過 長産生熱量時,易發生銅箔膨脹和脫落現象,如


必須使用大面積銅箔時,可採用柵格狀導 線。導線的埠則是焊盤。焊盤中心孔要比器件引線直徑大一些。焊


盤太大在焊接中易形成 虛焊,焊盤外徑


D


一般不小於(


d



1.2



mm< /p>


,其中


d


爲孔徑,對於一些密度比較大的


元件的焊盤最小直徑可取(


d+1.0



mm


,焊盤設計完成後,要在印製板的焊盤周圍畫上器件的外 形框,同時


標注文字和字元。


一般文字或外框的高度應該在


0.9mm


左右,


線寬應該在


0.2mm


左右。


並且標注文字和字元


等線不要壓在焊盤上。如果爲雙層板,則底層字元應該鏡像標注。




二、爲了使所設計的産品更好有效地工作,

< br>PCB


在設計中不得不考慮它的抗幹擾能力,並且與具體的電路有


著密切的關係。



線路板中的電源線、


地線等設計尤爲重要,根據不同的電路板流過電流的大小,儘量加大電源線的寬度,

從而來減小環路電阻,


同時電源線與地線走向以及資料傳送方向保持一致。


有助於電路的抗雜訊能力的增強。


PCB


上即有 邏輯電路又有線性電路,使它們儘量分開,低頻電路可採用單點並聯接地,實際佈線可把部分串

< br>聯後再並聯接地,高頻電路採用多點串連接地。地線應短而粗,對於高頻元件周圍可採用柵格大面積地箔,


地線應儘量加粗,如果地線很細的導線,接地電位隨電流的變化,使抗噪性能降低。因此 應加粗接地線,使


其能達到三位於電路板上的允許電流。


如果設 計上允許可以使接地線在


2-3mm


以上的直徑寬度,


在數位電路


中,其接地線路布成環路大多能提高抗雜訊能力。

< p>
PCB


的設計中一般常規在印製板的關鍵部位配置適當的退


藕電容。


在電源入端跨線接


10-100uF


的電解電容,


一般在


20-30


管腳的附近,


都應佈置一個


0.01PF


的瓷片電


容,


一般在


20- 30


管腳的積體電路晶片的電源管腳附近,


都應佈置一個


0.01PF


的磁片電容,


對於較大的晶片,


電源引腳會有幾個,最好在它們附近都加一個退藕電容,超過


2 00


腳的晶片,則在它四邊上都加上至少二個


退藕電容。如果空 隙不足,也可


4-8


個晶片佈置一個


1 -10PF


鉭電容,對於抗幹擾能力弱、關斷電源變化大的


元件 應在該元件的電源線和地線之間直接接入退藕電容,以上無論那種接入電容的引線不易過長。



三、線路板的元件和線路設計完成後,接上來要考慮它 的工藝設計,目的將各種不良因素消滅在生産開始之


前,同時又要兼顧線路板的可製造性 ,以便生産出優質的産品和批量進行生産。



前面在說元件得定 位及佈線時已經把線路板的工藝方面涉及到一些。線路板的工藝設計主要是把我們設


計出 的線路板與元件通過


SMT


生產線有機的組裝在一起,


從而實現良好電氣連接達到我們設計産品的位置佈


局。

< br>焊盤設計,


佈線以抗幹擾性等還要考慮我們設計出的板子是不是便於生産,


能不能用現代組裝技術-


SMT


技術進行組裝 ,同時要在生産中達到不讓産生不良品的條件産生設計高度。具體有以下幾個方面:


< /p>


1


:不同的


SMT


生產線有各自不同的生産條件,但就


PCB


的大小,


pcb


的單板尺寸不小於


200*150mm< /p>



如果長邊過小可以採用拼版,


同時長與 寬之比爲


3



2



4



3


電 路板面尺寸大於


200×


150mm


時 ,應考慮電路


板所受的機械強度。



2


:當電路板尺寸過小,對於


SMT


整線 生産工藝很難,更不易於批量生産,最好方法採用拼板形式,就


是根據單板尺寸,把


2


塊、


4


塊、


6


塊等單板組合到一起,構成一個適合批量生産的整板,整板尺寸要 適合可


貼範圍大小。



3


:爲了適應生產線的貼裝,單板要留有


3-5mm


的 範圍不放任何元件,拼板留有


3-8mm


的工藝邊,工藝


邊與


PCB


的連接有三種形式:


A


無搭邊,有分離槽,


B


有 搭邊,又有分離槽,


C


有搭邊,無分離槽。設有沖


裁用工藝搭國。根據


PCB


板的外形,有途等適用不 同的拼板形式。對


PCB


的工藝邊根據不同機型的定位方


式不同,有的要在工藝邊上設有定位孔,孔的直徑在


4-5

< p>
釐米,相對比而言,要比邊定位精度高,因此有定

:爲了更好的定位和實現更高的貼裝精度,要爲


PCB


設上基準點,有無基準點和設的好與壞直接影響



S MT


生產線的批量生産。基準點的外形可爲方形、圓形、三角形等。並且直徑大約在


1-2mm


範圍之內,


在基準點的周圍要在


3-5mm


的範圍之內,不放任何元件和引線。同時基準點要光 滑、平整,不要任何污染。


基準點的設計不要太靠近板邊,要有


3-5mm


的距離。



5


:從整體生産工藝來說,其板的外形最好爲距形,特別對於波峰焊。採用矩形便於傳送。如果


PCB



有缺槽要用工藝邊的形式補齊缺槽,對 於單一的


SMT


板允許有缺槽。但缺槽不易過大應小於有邊長長 度的


1/3




總之,不良品的産生是每一個環節都有可能,但就

板設 計這個環節,應該從



各個方面去考慮,讓其即

一、檢查內容




1


)元件有無遺漏。



2


)元件有無貼錯。



3


)有無短路。



4


)有無虛焊。



前三種情況卻好檢查 ,原因也很清楚,很好解決,但虛焊的原因卻是比較複雜。




二、虛焊的判斷



1

< br>、採用在線測試儀專用設備(俗稱針床)進行檢驗。



2


、目視(含用放大鏡、顯微鏡)檢驗。當目視發現焊點焊料過少焊錫浸潤不良,或焊點中 間有斷縫,或焊錫


表面呈凸球狀,或焊錫與


SMD


不相親融等,就要引起注意了,即便輕微的現象也會造成隱患,應立即


判斷是 否是存在批次虛焊問題。判斷的方法是:看看是否較多


PCB


上 同一位置的焊點都有問題,如只是


個別


PCB

< br>上的問題,可能是焊膏被刮蹭、引腳變形等原因,如在很多


PCB


上同一位置都有問題,此時


很可能是元件不好或焊盤有問題造成的。

< p>



三、虛焊的原因及解決



1

< p>
、焊盤設計有缺陷。焊盤上不應存在通孔,通孔會使焊錫流失造成焊料不足;焊盤間距、面積也需要 標準匹


配,否則應儘早更正設計。



2



PCB


板有氧化現象,即焊盤發烏不 亮。如有氧化現象,可用橡皮擦去氧化層,使其亮光重現。


PCB


板受


潮,如懷疑可放在乾燥箱內烘乾。


PCB


板有油漬、汗漬等污染,此時要用無水乙醇清洗乾淨。



3


、印過焊膏的


PCB


,焊膏被刮、 蹭,使相關焊盤上的焊膏量減少,使焊料不足。應及時補足。補的方法可用


點膠機或用竹 簽挑少許補足。

SMD


(表面貼裝元器件)質量不好、過期、氧化、 變形,造成虛焊。這是較多見的原因。



1



氧化的元件發烏不亮。


氧化物 的熔點升高,


此時用三百多度度的電鉻鐵加上松香型的助焊劑能焊接,

< br>但用二百多度的


SMT


回流焊再加上使用腐蝕性較弱的免 清洗焊膏就難以熔化。故氧化的


SMD



不宜用再流焊爐焊接。買元件時一定要看清是否有氧化的情況,且買回來後要及時使用。同理,


氧化的焊膏也不能使用。




2


)多條腿的表面貼裝元件,其腿細小,在外力的作用下極易變形,一旦變形,肯定會發 生虛焊或缺焊


的現象,所以貼前焊後要認真檢查及時修復。





施加焊膏的通用工藝




/smtzl_




一:工藝目的



把適量的


Sn/Pb


焊膏均勻地施加在


PCB


焊盤上,以保證貼片元件與


PCB


相對應的焊盤達到良 好的電氣連接,


並具有足夠的機械強度。





二:技術要求



1

:施加的焊膏量均勻,一致性好。焊盤圖形要清晰,相鄰的圖形之間儘量不要粘連。焊膏圖形與焊盤圖形要< /p>


一致,儘量不要錯位。



2


:在一般情況下,焊盤上單位面積的焊膏量應爲


0.8mg/



2


左右。對窄間距元器件,應爲

0.5mg/



2


左右。



3


:印刷在基板上的焊膏與希望重量值相比, 可允許有一定的偏差,至於焊膏覆蓋每個焊盤的面積應在


75



以上。採用免清洗技術時,要求焊膏全部位元元元元元元元元於焊盤上。



4


:焊膏印刷後,應無嚴重塌落,邊緣整齊,錯位不 大於


0.2


㎜,對窄間距元器件焊盤,錯位不大於


0.1


㎜。


基板表面不允許被焊膏污染。採用免清洗 技術時,可通過縮小模板開口尺寸的方法,使焊膏全部


位元元元元元元元元於焊盤上。< /p>




三:施加焊膏的方法和各種方法的適用範圍


< br>施加焊膏的方法有兩種:滴塗式(即注射式,滴塗式又分爲手動和自動滴塗機兩種方法)

< br>、金屬模板印刷。兩
