Waxaa jira noocyo badan oo loox wareeg ah oo suuqa ku jira, ereyada xirfadeedna way kala duwan yihiin, waxaana ka mid ah guddiga fpc aad loo isticmaalo, laakiin dad badan ayaan wax badan ka aqoon guddiga fpc, haddaba maxay ka dhigan tahay guddiga fpc?
1, guddiga fpc waxaa sidoo kale loo yaqaan "board circuit dabacsanaan", waa mid ka mid ah guddiga wareegga daabacan ee PCB, waa nooc ka mid ah isticmaalka walxaha dahaadhka ah sida substrate, sida: polyimide ama polyester film, ka dibna iyada oo loo marayo hab gaar ah oo la sameeyay. ee looxa wareegga daabacan. Cufnaanta fiilooyinka ee guddiga wareegtadan guud ahaan waa mid aad u sarreeya, laakiin miisaanku wuxuu noqon doonaa mid khafiif ah, dhumucdiisuna waxay noqon doontaa mid khafiif ah, oo leh waxqabad dabacsanaan wanaagsan, iyo sidoo kale waxqabad foorarsi wanaagsan.
2, fpc board iyo guddiga PCB waa farqi weyn. Substrate-ka guddiga fpc guud ahaan waa PI, sidaas darteed si sabab la'aan ah ayaa loo qaloocin karaa, u rogi karaa, iwm., halka substrate-ka guddiga PCB uu guud ahaan yahay FR4, sidaas darteed ma noqon karo mid qaloocsan oo qallafsan. Sidaa darteed, isticmaalka iyo goobaha codsiga ee guddiga fpc iyo guddiga PCB sidoo kale aad bay u kala duwan yihiin.
3, sababtoo ah guddiga fpc waa la foorarsan karaa oo la rogi karaa, guddiga fpc ayaa si weyn loogu isticmaalaa booska u baahan in si isdaba joog ah loo leexiyo ama isku xirka qaybo yaryar. Guddiga PCB waa mid adag, sidaas darteed si weyn ayaa looga isticmaalaa meelaha qaarkood oo aan loo baahnayn in la foorarsado oo xooggu uu yahay mid adag.
4, guddiga fpc leeyahay faa'iidooyinka ee size yar yar, miisaanka fudud, si ay si wax ku ool ah u dhimi kartaa size ee alaabta elektarooniga ah waa mid aad u yar, sidaas darteed waxaa si ballaaran loo isticmaalaa in warshadaha telefoonka gacanta, warshadaha kombiyuutarka, warshadaha TV, warshadaha camera digital iyo kuwa kale. warshad wax soo saarka elegtarooniga ah oo aad u yar, aad u casrisan.
5, guddiga fpc ma aha oo kaliya in si xor ah u foorarsado, laakiin sidoo kale si aan macquul ahayn loo dhaawaco ama la iskula duubo, sidoo kale si xor ah ayaa loo habayn karaa iyadoo loo eegayo baahiyaha qaabka booska. Meesha saddex-geesoodka ah, guddiga fpc sidoo kale waxaa loo dhaqaajin karaa si sabab la'aan ah ama telescoped, si ujeedada isdhexgalka loo gaaro inta u dhaxaysa fiilada iyo isku dhafka qaybta.
Waa maxay filimada qalalan ee PCB?
1, PCB hal dhinac ah
Saxanka salku waxa uu ka samaysan yahay xaashi phenol copper laminated board (warqad phenol ah oo sal ah, oo lagu dahaadhay bireed naxaas ah) iyo warqad Epoxy copper laminated. Intooda badan waxaa loo isticmaalaa wax soo saarka korontada gudaha sida raadiyaha, qalabka AV, kuleyliyeyaasha, talaajadaha, mashiinada dharka, iyo mashiinada ganacsiga sida madbacadaha, mashiinada iibka, mishiinada wareegyada, iyo qaybaha elektarooniga ah.

Maaddada salka ayaa inta badan ah Glass-Epoxy ama resin benzene. Inta badan loo isticmaalo kombuyuutarrada gaarka ah, Me (elektrooniga caafimaadka, elektiroonigga caafimaadka) mishiinnada, mashiinnada cabbiraadda, mishiinnada tijaabinta semiconductor, NC (Control Numerical) mashiinnada, furayaasha elektaroonigga ah, mashiinnada isgaarsiinta, looxyada wareegga xusuusta, kaararka IC, iwm, waxaa jira sidoo kale muraayadda naxaasta synthetic ee looxa dahaadhay sida qalabka PCB multi-lakabka ah, Inta badan diiradda on sifooyinkiisa processing aad u fiican.
4,6-8 lakab oo PCB ah
Walxaha salku wali waxay ku salaysan yihiin glass-epoxy ama galaas benzene resin. Loo isticmaalo shixnadaha elektaroonigga ah, mishiinnada tijaabinta semiconductor, kombiyuutarada shakhsi ahaaneed ee dhexdhexaadka ah, EWS (EngineeringWorkStation), NC iyo mashiino kale.
5, in ka badan 10 lakab oo PCB ah
Substrate-ka waxaa inta badan laga sameeyaa galaas benzene resin, ama GLASS-epoxy oo ah walxo badan oo PCB ah. Codsiga PCB-ga noocaan ah waa mid gaar ah, badankooduna waa kombuyuutar waaweyn, kombiyuutarro xawaarihiisu sarreeyo, mashiinnada isgaarsiinta, iwm.
6, walxaha kale ee substrate PCB
Alaabta kale ee PCB waa substrate aluminium, substrate bir iyo wixii la mid ah. Wareegga waxaa lagu sameeyay substrate-ka, kuwaas oo intooda badan loo isticmaalo baabuurka leexashada (matoorada yaryar). Intaa waxaa dheer, waxaa jira PCB dabacsan (FlexiblPrintCircuitBoard), wareegga waxaa la sameeyay on polymer ah, polyester iyo waxyaabaha kale ee muhiimka ah, waxaa loo isticmaali karaa sida hal lakab, lakabka double, in guddiga multi-lakabka noqon kartaa. Boodhkan wareegga ah ee dabacsan ayaa inta badan loo isticmaalaa qaybaha dhaqaaqa ee kamaradaha, mishiinnada OA, iwm, iyo xidhiidhka ka dhexeeya PCB adag ama isku dhafka waxtarka leh ee ka dhexeeya PCB adag iyo PCB jilicsan, sida habka isku dhafka isku dhafka ah sababtoo ah sare barti, qaabkeedu waa kala duwan yahay.
Guddi lakabyo badan iyo saxan TG dhexdhexaad ah iyo sare
Marka hore, looxyada wareega ee PCB-da lakabka ah ayaa guud ahaan loo adeegsadaa aagagee?
Looxyada wareega ee PCB-ga Multilayer waxaa guud ahaan loo adeegsadaa qalabka isgaarsiinta, qalabka caafimaadka, kantaroolka warshadaha, amniga, qalabka elektiroonigga ah, duulista, meelaha kombayuutarka; Sida "awoodda muhiimka ah" ee dhinacyadan, oo leh kororka joogtada ah ee hawlaha alaabta, khadadka cufan oo badan, shuruudaha suuqa ee tayada guddiga ayaa sidoo kale sii kordhaya oo sarreeya, iyo baahida macaamiisha ee dhexdhexaadka iyo sare. Looxyada wareegga TG ayaa si joogto ah u kordhaya.
Marka labaad, gaar ahaan looxyada wareegga PCB-da lakabka badan
Guddiga PCB-ga caadiga ah waxay yeelan doonaan qallafsanaan iyo dhibaatooyin kale marka heerkulku sarreeyo, halka sifooyinka farsamada iyo korantada ay sidoo kale hoos u dhici karaan si aad ah, hoos u dhigaya nolosha adeegga alaabta. Beerta codsiga ee guddiga PCB-da lakabka badan ayaa guud ahaan ku yaala warshadaha tignoolajiyada-dhamaadka sare, taas oo si toos ah u baahan in guddiga uu leeyahay xasilooni sare, caabbinta kiimikada sare, oo u adkeysan kara heerkulka sare, huurka sare iyo wixii la mid ah.
Sidaa darteed, wax soo saarka ee looxyada PCB multi-lakabka isticmaalaa ugu yaraan TG150 taarikada, si loo hubiyo in guddiga wareegga la dhimay by arrimo dibadda ee habka codsiga iyo kordhiyo nolosha adeegga alaabta.
Saddexaad, xasilloonida nooca saxanka sare ee TG iyo kalsoonida sare
Waa maxay qiimaha TG?
Qiimaha TG: TG waa heerkulka ugu sarreeya ee xaashidu ay ku sii adkaysato, qiimaha TG-na waxaa loola jeedaa heerkulka uu polymer-ka amorphous (oo ay ku jiraan qaybta amorphous ee polymer-ka crystalline) uu ka soo wareego gobolka dhalada ah una guuro heerka sare ee laastikada (caag. gobolka).
Qiimaha TG waa heerkulka muhiimka ah ee substrate-ku uu ka dhalaalayo dareeraha caag ah.
Heerka qiimaha TG wuxuu si toos ah ula xiriira xasiloonida iyo isku halaynta alaabta PCB, iyo sare u kaca qiimaha TG ee guddiga, ayaa sii xoogeysanaya xasilloonida iyo isku halaynta.
Xaashida sare ee TG waxay leedahay faa'iidooyinka soo socda:
1) Iska caabbinta kulaylka sarreeya, kaas oo yarayn kara sabaynta suufka PCB inta lagu jiro dhalaalidda kulul ee infrared, alxanka iyo shoogga kulaylka.
2) Heerarka balaadhinta kulaylka hooseeya (CTE hoose) waxay yareyn kartaa qulqulka ay sababaan xaaladaha heerkulka, waxayna yareyn kartaa jabka naxaasta ee cidhifka godka ay sababto balaadhinta kulaylka, gaar ahaan looxyada PCB ee leh sideed lakab ama ka badan, waxqabadka lagu dhejiyay godadka wuu ka fiican yahay ta looxyada PCB ee leh qiyamka guud ee TG.
3) Waxay leedahay iska caabin kiimikaad oo heer sare ah, si guddiga PCB loo qooyay habka daaweynta qoyan iyo xalal kiimiko oo badan, waxqabadkeedu weli waa mid taagan.
