Sababta asalka u ah soo bixitaankii iyo dhicitaankii waxaa lagu go'aamiyaa sifooyinka mid ah waxyaabaha la. Si loo xaliyo dhibaatada yaraanshaha oo ka mid ah Guddiga adag-debecsan PCB , aynu hordhac kooban oo si wax ku of saxan Polyimide ka dabacsan:
(1) polyimide uu leeyahay qaab ciyaareed aad u fiican kaamerada, adkeysan karaan si lama filaan ah kaamerada of daaweyn kulaylka kabida, lead-free;
(2) Inta badan saarayaasha qalabka u muuqdaan in ay isticmaalaan guddiga wareeggeedii dabacsan qalabka yaryar ee u baahan in ay xoogga saaraan daacadnimada signal;
(3) Polyimide leeyahay heerkul guurka galaas sare iyo sifooyinka dhibic barafku sare,
xaaladaha caadiga ah si loo hawl at 350 ℃ ama in ka badan,
(4) In diridda organic, polyimide waa beelaya in dareeraha wax caadi ah organic.
wax saxan dabacsan kor iyo hoos wax salka PI muhiimsan iyo xabagta xiriir, in uu yahay, xiriir weyn la imidation ee PI, sare ee heerka imidization, xoog controllability ah.
Sida uu qabo xeerka soo-saarka caadiga ah, ka dib markii guddiga dabacsan goynta, iyo formation of khadka naqshadeynta, iyo isku dhafka ah ee adag iyo jilicsan ee geedi socodka of riixo yeelan doonaan heerar kala duwan ee koritaanka iyo foosha in naqshadeynta Iagu khadka, xoojinta line iyo jihada , waxay keeni doontaa in jaheeyo ee stress, oo loox oo dhan, iyo ugu danbeyn keeni xeerka guud ee guddiga kor iyo hoos isbedel; in geeddi-socodka ah ee isku jilicsan iyo mid adag, sida dusha sare daboolaya filimada iyo saldhig wax Wehliyaha ballaarinta PI waa khilaafsan, baaxadda shahaado qaar ka mid ah ballaarinta gudahood.
Laga soo bilaabo sabab dabeecadda, wax kasta oo kordhay iyo waxaa saameeya heerkulka iyo, iyada oo sababtu tahay dheer in wax soo saarka PCB habka, waxyaabaha ka dib markii geedi socodka badan oo kulul oo qoyan, qiimaha yaraanshaha sare yeelan karaan darajooyinka kala duwan ee daahsoon, laakiin muddo dheer oo dhabta ah waayo-aragnimo wax soo saarka, isbeddel ama joogto ah.
Sida loo xakameeyo oo loo hagaajiyo?
Si adag u hadlayay, stress gudaha ah oo duudduuban kasta oo wax waa ka duwan yahay, oo ay gacanta ku habka of Dufcaddii kasta oo bir si sax ah isku mid ma noqon doono. Sidaa darteed, ay gacanta of Wehliyaha ee ballaarinta wax ku salaysan tahay tiro badan oo ah saldhig tijaabo On gacanta ku habka iyo falanqaynta xogta tirakoobka si gaar ah muhiim. In hawlgalka dhabta ah, yaraanshaha ee ahaa wasladdii khafiifka dabacsan u qaybsan yahay marxaladood:
The ugu horeysay waxa uu ka yimid furitaanka inay sheet dubista, Heerkan waxa loo inta badan sababa saamaynta heerkulka:
Si loo hubiyo in saxan dubista sababa soo bixitaankii iyo dhicitaankii ah xasiloonida, marka hore si loo farsameeyo joogta ah gacanta, hoos u weeyn ee wax lagu midaysan yahay, saxan dubista kasta kululaynta iyo qaboojinta hawlgallada waa in uu ahaadaa joogto ah, oo aan ku Daynanaa Iyagoo ku eryan hufnaan, iyo saaray dhammeeyayna ay taarikada hawada ee dhereg badan kulayl. Sida kaliya ee si loo yareeyo cadaadiska gudaha sababa ballaarinta iyo foosha qalab.
The labaad wajiga ka dhacay hanaanka wareejinta hannaankii. Yaraanshaha ee marxaladan waxaa inta badan ay keento isbeddel ah ee orientation stress in waxyaabaha la.
Si loo hubiyo in hanaanka wareejinta line waa mid deggan, Dhammaan waraaqaha dubista ma noqon karaan ilka, si toos ah u dhex-daaweyn pre dusha line nadiifinta kiimikada, ka dib markii dusha xuub cadaadis waa heerka off, guddiga dusha taagan ka hor iyo ka dib markii gaadhista waa in ay ahaadaan ku filan , ka dib markii suuqa kala iibsiga dhamaad ah, ay sabab u tahay isbedelka of hanuuninta walwalka, saxan dabacsan bandhigi doonaa shahaado kala duwan ee crimp iyo foosha, sidaas xiriir magdhow film control of line u adag oo jilicsan isku dhafan oo sax ah ee gacanta ku, at waqti isku mid ah, dabacsan saxan kordhay iyo ascertainment of kala duwan ee qiimaha, waa wax soo saarka ee ay taageerada ku salaysan xogta guddi adag.
The saddexaad wajiga of foosha ku dhacdaa habka saxaafadda guddiga adag oo jilicsan, ku soo koobin riixo ugu weyn oo guryaha wax of heerkan waa go'an.
ARIMAHA RAADAYNAYA wajiga this of ballaarinta waxaa ka mid ah heerka kuleylka ee dukumiintiyo, goob argument cadaadiska, iyo heerka copper haraaga ah oo dhumucdiisuna waxay of xudunta u ah. Guud ahaan, heerka yaryar ee haraaga ah copper, weyn ee qiimaha yaraanshaha ah; ka khafiifsan asaasiga ah, ugu weyn qiimaha soo bixitaankii iyo dhicitaankii. Si kastaba ha ahaatee, ka weyn in yar, waa hab si tartiib ah, si magdhow film si gaar ah muhiim. Intaa waxaa dheer, ay sabab u tahay dabeecadda oo ka mid ah guddiga dabacsan iyo guddiga adag qalab, ay magdhow waa arrin kale oo u baahan in la tixgeliyo.
