Tiknoolajiyada ugu fiican waa mid ka mid ah soosaarayaasha pcb ugu fiican iyo alaab-qeybiyeyaasha guddiga wareegyada daabacan ee Shiinaha
Dhulka baaxadda leh ee injineernimada iyo wax-soo-saarka, waxa jira duni daahsoon oo godad ah, mid walbana ujeeddadeeda iyo mawqifkeeda gaarka ah leh. Dalooladani waxay door muhiim ah ka ciyaaraan fududaynta hawlaha kala duwan ee hababka makaanikada iyo elektiroonigga ah. Blog-kan, waxaan ka gali doonaa safar si aan u sahamiyo noocyada kala duwan ee godadka ku jira sabuuradaha wareegga daabacan. Markaa, xidh suunkaaga oo aynu u dhex galno aduunka xiisaha leh ee sifooyinkan injineernimada ee muhiimka ah.
Noocyada Guud ee Godadka PCB
Marka la eego looxa wareegga, qofku wuxuu ogaan doonaa godad badan oo u adeegaya ujeedooyin gaar ah. Kuwaas waxaa ka mid ah Via godad, PTH, NPTH, godad indho la'aan, godad la aasay, godadka ka soo horjeeda, godadka Countersunk, godadka goobta, iyo godad Fiducial. Nooc kasta oo dalool ah wuxuu buuxiyaa door gaar ah iyo shaqada PCB dhexdeeda, taasoo ka dhigaysa muhiim in la is barto sifooyinkooda si loo fududeeyo naqshadaynta PCB ee ugu habboon.
1. Via Godad
Godadku waa daloolo yaryar oo isku xidha lakabyada kala duwan ee looxa wareegga daabacan (PCB). Waxay fududeeyaan socodka calaamadaha iyo awoodda u dhexeysa lakabyada, taas oo u sahlaysa naqshadaynta wareegga iyo gudbinta hufan. Vias waxaa loo kala saari karaa laba nooc: Plated through-holes (PTH) iyo non-plated through-holes (NPTH), mid kastaa wuxuu u adeegaa hawlo kala duwan.
2. PTH (Dool-Lool)
Godad-daahsan (PTH) waa fiisooyin ay ku jiraan walxo dahaadhan derbiyada gudaha. PTH-yadu waxay sameeyaan isku xirka korantada ee u dhexeeya lakabyada kala duwan ee PCB, taas oo u oggolaanaysa marinka calaamadaha iyo awoodda. Waxay door muhiim ah ka ciyaaraan isku xirka qaybaha, fududaynta socodka korantada, iyo hubinta shaqaynta wareegga.
3. NPTH (Dool aan ku dahaadhayn)
Godadka aan dahaadhka ahayn (NPTH) ayaa ka maqan dahaarka korantada ee derbiyadooda gudaha, taas oo ka dhigaysa inay ku habboon yihiin ujeedooyin farsamo oo keliya. Daloolladaan waxaa loo isticmaalaa taageero farsamo, toosin, ama hagayaal meeleyn, iyada oo aan la samayn wax xiriir koronto ah. NPTHs waxay bixiyaan xasillooni iyo sax, hubinta in si habboon loo waafajiyo qaybaha gudaha guddiga wareegga. Waxa ugu badan ee u dhexeeya PTH iyo NPTH waa bireedyada naxaasta ah ayaa lagu dhejin doonaa gidaarka daloolka halka NPTH aan loo baahnayn in la sameeyo saxan.
4. Godad indho la'aan
Godad indho la'aan ah ayaa qayb ka mid ah godad la jeexjeexay kuwaas oo gala hal dhinac oo kaliya ee looxa wareegga. Waxay ugu horreyntii u shaqeeyaan si ay ugu xidhaan lakabka sare ee looxa iyo lakabka gudaha, awood u yeelashada qaybuhu inay ku dhejiyaan hal dhinac inta ay ka qarsoon yihiin kan kale. Godad indho la'aan waxay bixiyaan kala duwanaansho waxayna gacan ka geystaan kordhinta booska naqshadaha guddiga wareegga adag.
5. Godad la aasay
Godad la aasay ayaa gabi ahaanba lagu xidhay gudaha looxa wareegga, iyaga oo isku xidhaya lakabyada gudaha iyada oo aan la sii kordhinayn lakabyada dibadda. Godadadaasi waxay ka qarsoon yihiin labada dhinac ee looxa waxayna u adeegaan si ay u abuuraan isku xirka iyo dariiqyada u dhexeeya lakabyada gudaha. Godad la aasay ayaa u oggolaanaya naqshadaynta guddiga wareegga cufan, yaraynta kakanaanta raadadka marinka iyo kor u qaadida shaqada guud ee guddiga. Waxay bixiyaan xal aan kala go 'lahayn oo cufan iyada oo aan la soo bandhigin dusha sare.
6. Godad counterbore
Daloollada ka-hortagga waa meelo wareegyo ah oo loo sameeyay si ay u dajiyaan madaxyada boolal, nuts, ama boolal. Waxay bixiyaan dalool hoose oo fidsan kaas oo u oggolaanaya xidhidhiyeyaasha inay fadhiistaan si fiican ama wax yar ka hooseeya dusha alaabta. Shaqada aasaasiga ah ee godadka counterbore waa in kor loo qaado bilicda iyo shaqeynta naqshadeynta iyadoo la siinayo muuqaal siman iyo xitaa. Dalooladan waxaa badanaa laga helaa alwaax-sameynta, biraha, iyo codsiyada injineernimada halkaasoo la rabo meel qarsoon ama ka weyn
7. Godadka Countersunk
Godad Countersunk waa meelo conical ah oo loogu talagalay in lagu xareeyo madaxyada boolal ama xidheyaashooda xaglaha ah. Waxaa loo shaqeeyaa si ay u hubiyaan in madaxyada isboodhka ahi ay si fiican u jiifaan ama wax yar ka hooseeyaan alaabta. Godadka Countersunk waxay u adeegaan ujeeddooyin qurux badan iyo kuwo wax ku ool ah labadaba, iyagoo siinaya dhammayn quruxsan oo aan cillad lahayn iyadoo la yareynayo khatarta qulqulka ama soo bixista. Kala duwanaanshahooda ayaa ka dhigaya kuwo ku habboon codsiyada kala duwan, laga bilaabo soo saarista alaabta guryaha ilaa injineernimada hawada sare.
8. Godadka Goobta
Godadka Goobta, oo sidoo kale loo yaqaanno Godadka Tixraaca ama Godadka Qalabka, waxay u adeegaan sida qodobbada tixraaca ee toosinta iyo meelaynta qaybaha, qaybaha, ama qalabyada inta lagu jiro habka wax soo saarka ama isku-ururinta. Daloolladan si istiraatiji ah ayaa loogu meeleeyay nakhshad si loo hubiyo in si sax ah oo joogto ah loo siman yahay, awoodna u siinaya isu imaatinka hufan iyo yaraynta khaladaadka.
9. Godad Fiducial
Godad Fiducial, oo sidoo kale loo yaqaan Calaamadaha Fiducial ama Calaamadaha Is-waafajinta, waa godad yar oo sax ah ama calaamado lagu dhejiyay dusha sare ama PCB (Guddiga Wareegga Daabacan). Dalooladani waxay u adeegaan sida qodobbada tixraaca muuqaalka ee nidaamka aragga, hababka otomaatiga ah, ama kamaradaha aragga mashiinka.
Markaan soo gabagabeyno safarkeena aduunka xiisaha leh ee godadka injineernimada, waxaan helnay faham qoto dheer oo ku saabsan shaqooyinka iyo boosaska godadka counterbore, godadka countersunk, iyada oo loo marayo godadka, PTH, NPTH, godadka indhoolaha, iyo godadka la aasay. Godadkani waa walxo lagama maarmaan u ah warshado kala duwan, waxna ka tara bilicda, shaqaynta, iyo hufnaanta naqshadaha.
Ka dib marka aad mid kasta soo bandhigto, waxa ay ahayd in aad si qoto dheer u fahanto hawlahooda, waxa aad rajaynaysaa in tani ay ku caawinayso godadka naqshadaynta mashruucaaga PCB!!
