Tiknoolajiyada ugu fiican waa mid ka mid ah soosaarayaasha pcb ugu fiican iyo alaab-qeybiyeyaasha guddiga wareegyada daabacan ee Shiinaha
Marka ay timaado godadka PCB-yada (Printed Circuit Boards), waxaa laga yaabaa in qof had iyo jeer xiiseeya laba god oo gaar ah: godka Counterbore iyo Countersunk hole. Way fududahay in lagu jahawareeriyo oo si sahlan loo fahmo haddii aad tahay qof caadi ah oo PCB ah. Maanta, waxaan soo bandhigi doonaa farqiga u dhexeeya counterbore iyo countersunk wixii tafaasiil ah, aan sii wadno akhrinta!
Waa maxay Godka-ka-hortagga?
Godka counterbore waa nasasho cylindrical ah oo saaran PCB kaas oo leh dhexroor weyn oogada sare iyo dhexroor yar xagga hoose. Ujeedada dalool counterbore waa in loo sameeyo meel bannaan oo madaxa birta ah ama garabka boodhka, taasoo u oggolaanaysa inuu ku fadhiisto mid ama wax yar ka hooseeya dusha PCB-ga. Dhexroorka weyn ee sare wuxuu qaadaa madaxa ama garabka, halka dhexroorka yar uu hubinayo in usheeda dhexe ama jirku si fiican ugu habboon yahay.
Waa maxay Countersunk Hole?
Dhanka kale, daloolka countersunk waa meel nasasho ah oo koleej ah oo saaran PCB kaas oo u oggolaanaya madaxa furaha ama boodhka inuu ku fadhiisto dusha PCB. Qaabka daloolka countersunk wuxuu la mid yahay astaanta madaxa xiraha, taasoo abuureysa meel aan simaneyn oo siman marka furka ama boodhka si buuxda loo geliyo. Godadka Countersunk waxay caadi ahaan leeyihiin dhinac xaglo leh, badiyaa 82 ama 90 darajo, taas oo go'aamisa qaabka iyo cabbirka madaxa xiraha ee ku haboonaan doona fasaxa.
Counterbore VS Countersunk: Joometri
Halka ay labaduba u adeegaan godadka xidhidhayaasha, kala duwanaanshahooda ugu weyni waxa uu ku jiraa joomatarigooda iyo noocyada xidhidhka ay dejiyaan.
Godad ka soo horjeeda waxay leeyihiin nasasho cylindrical ah oo leh laba dhexroor oo kala duwan, halka godadka countersunk ay leeyihiin nasasho conical ah oo leh dhexroor keliya.
Daloollada ka soo horjeeda waxay abuuraan gobol la talaabsado ama kor loo qaaday oogada PCB-ga, halka godadka-dalooladu ay ka dhashaan biyo-soo-bax ama dib-u-dhac.
Counterbore VS Countersunk: Noocyada xidhaha
Daloollada ka-hortagga waxa ugu horrayn loo adeegsadaa xirayaasha leh madaxa ama garabka, sida boolal ama boolal u baahan korka adag.
Daloollada ka-hortagga waxaa loogu talagalay xirayaasha leh madax-toos ah, sida boolal fidsan ama boolal-iska-celiya, si loo gaaro meel nadiif ah.
Counterbore VS Countersunk: xaglaha qodista
Cabirrada kala duwan iyo xaglaha qodista ee qashin-qubka ayaa la bixiyaa si loo soo saaro mashiinnada miiska, iyadoo ku xiran isticmaalka loogu talagalay. Xaglahaan waxaa ka mid noqon kara 120°, 110°, 100°, 90°, 82°, iyo 60°. Si kastaba ha ahaatee, xaglaha qodista ee ugu badan ee lagu shaqaysto counter-sinking waa 82° iyo 90°. Si loo helo natiijooyinka ugu wanaagsan, waxaa lama huraan ah in la toosiyo xagasha countersink-ka iyo xagasha duuban ee dhinaca hoose ee madaxa xiraha. Dhanka kale, godadka ka-hortagga waxay ka kooban yihiin dhinacyo isbar-bar socda oo aan qasab ahayn in la duubo.
Counterbore VS Countersunk: Codsiyada
Doorashada u dhaxaysa godadka counterbore iyo countersunk waxay ku xiran tahay shuruudaha gaarka ah ee naqshadeynta PCB iyo qaybaha la isticmaalayo.
Daloollada ka-hortagga waxay ka helaan codsiyada xaaladaha ay u baahan yihiin xidhid ammaan ah oo nadiif ah oo ka kooban qaybaha ama taargooyinka rakibidda. Waxa caadi ahaan loo isticmaalaa in lagu xidho xidhiyeyaasha, xidhmooyinka, ama PCB-yada xayndaab ama shasi.
Godadka Countersunk waxaa badanaa la shaqeeyaa marka tixgalinta bilicda ay muhiim tahay, maadaama ay bixiyaan oog siman oo siman. Waxaa inta badan loo isticmaalaa in lagu rakibo PCB-yada oogooyinka meelaha la doonayo dhamaystirka nadiifinta, sida qalabka elektarooniga ah ee macaamiisha ama codsiyada qurxinta.
Godadka ka-hortagga iyo daloolada countersunk ayaa ah astaamo muhiim u ah naqshadeynta PCB, taasoo awood u siinaysa kor-u-qaadidda qaybaha hufan iyo xirid sugan. Fahamka farqiga u dhexeeya labadan nooc ee godadka waxay u oggolaanaysaa naqshadeeyayaasha inay doortaan ikhtiyaarka ku habboon iyadoo lagu saleynayo shuruudaha gaarka ah ee codsiyadooda PCB. Haddi ay tahay hubinta isku xidhka sugan ama gaadhista dhammays araga lagu farxo, doorashada u dhaxaysa godadka counterbore iyo countersunk ayaa door muhiim ah ka ciyaara guud ahaan shaqaynta iyo bilicda golaha PCB.
