Solder Creeping Ebivaako & Ebigonjoolwa bya PTFE High-Temperature Tape

Nga ensibuko ey’ekikugu ekola olugoye olw’ebbugumu eringi olwa PTFE, Jiangsu Aokai New Materials egabana amakolero ag’ekikugu insights.Mu PCB empewo eyokya solder leveling, zaabu plating n'okunnyika zaabu enkola, solder creeping ku shielding edges za PTFE high-temperature tape okusinga kiva ku combined effect of physical okulemererwa tape n'enkola extreme process environments.

I. Ebivaako Solder Creeping

Edge warping of PTFE high-temperature tape forming gaps Mu kiseera ky’okufulumya ebbugumu eringi, empalirizo y’okusiiga ya tape ekendeera nga ebbugumu lirinnya. Bwe kiba nti okunyweza tekumala kuziyiza situleesi ya bbugumu, empenda za ttaapu zijja kuwuguka katono ne zikola ebituli by’emisuwa, kisobozese solder ow’amazzi okuyingira munda.

Wicking effect ne solder dam accumulation Solder etera okwekulukuunya ng’ayolekera ebitundu ebirimu ebbugumu eringi mu mubiri. Ekifo ekikuumibwa bwe kiba ku bbugumu erya waggulu ennyo, solder ey’amazzi erinnya waggulu ng’eyita mu bituli by’olutambi mu wicking eya bulijjo effect.Okugatta ku ekyo, PTFE tape enzito ennyo ejja kukola emitendera ku mbiriizi, kireete okukuŋŋaanyizibwa kwa solder okukola ddaamu ya solder, ekyongera okusajjula okuseeyeeya kwa solder.

Omutindo gw’ebintu ebitali bikwatagana ogwa PTFE high-temperature tape Oluwuzi olusiiga olwa PTFE tape eya wansi lutera okukulukuta, okwonooneka n’ebisigadde eby’okusiiga ku bbugumu erya waggulu. Tekoma ku kwonoona kiziyiza kya shielding, wabula era ecaafuwaza paadi, ekyongera nnyo obulabe bwa solder okwekulukuunya.

Obucaafu obuyita ku ttaapu ya PTFE Ne bwe kiba nti olutambi terufudde, okukutuka n’okumansa obululu bwa solder obusigadde mu PCB vias, oba obutundutundu obutonotono bwa solder obukolebwa flux vaporization mu kiseera ky’okusoda mu reflow, buyinza okuyingira oba okuyita mu kifo ekiziyiza ne kireeta obucaafu.

Lamination etali ntuufu n’okukyukakyuka kw’enkola Okulemererwa okuyonja kungulu ku shielding oba okunyiga obutamala nga osiiga tape kijja kuleka ebituli okusobola okuyingira mu solder.Okulinnya kw’ebbugumu okw’amangu ennyo mu kiseera ky’okusoda okuddamu okukulukuta kwongera nnyo ku mazzi ga solder, ekyanguyira okumenya ensalosalo ya PTFE tape.

Obutonnyeze obw’amaanyi obw’ebifo ebisiigiddwa zaabu ekyongera ku kizibu Ebifo ebya zaabu ebisiigiddwa zaabu n’eby’okunnyika birimu okufukirira okulungi ennyo mu solder. Solder bw’emala okukwatagana ne zaabu kungulu, esaasaana mangu ku mbiriizi za tape, ekivaamu ekifo ekinene ennyo eky’okuseeyeeya okusinga OSP n’enkola za bulijjo ez’okutereeza solder mu mpewo eyokya.

II. Ebigonjoolwa: Enteekateeka y’okukozesa entegeke ku ttaapu ya PTFE ey’omutindo ogwa waggulu

Londa ebintu ebirina ebisaanyizo era ossa omutindo ku nkola ya lamination Wettanire omutindo ogwa waggulu PTFE high-temperature tape eyakolebwa mu ngeri ey’enjawulo ku PCB high-temperature processes, n’ebbugumu resistance ya 250 ~ 260 °C okutuukiriza lead-free production requirements.Clean the shielding surface bulungi ne isopropanol nga tonnasiiga okukakasa full fitting awatali edge warping oba gaps. Yambala ggalavu ng’okola okwewala okufuuka giriisi.

Ziziyiza okumansa obululu bwa solder okumenya okuyita mu shielding Wettanira enkola ya solder paste efuumuuka entono era olongoose ebbugumu ly’okuddamu okukulukuta. Okubuguma okumala okwewala okufuumuuka kw’ekizimbulukusa mu ngeri ey’amaanyi era kikendeeza ku bulabe bw’obululu obutonotono obwa solder okumenya okuyita mu kiziyiza kya tape.

Okunyweza enzirukanya y’okukuba ebitabo n’okuyonja ebyuma Yoza stencil oluvannyuma lw’okukuba buli PCBs 2–3, era wettanire enkola y’okusiimuula enkalu + okuyonja mu vacuum okuziyiza ekikuta kya solder okumansira ku kifo kya tape.Bulijjo ggyawo butto wa solder asigadde ku kyuma ekikuba ebitabo, emitendera gy’okussa n’ebikozesebwa okumalawo obucaafu obw’okubiri.

Okulondoola omutindo gw’okuyingira n’enkola okukakali okusobola okukola ku buzibu bw’ebintu Yeetaaga abagaba PCB okuwa satifikeeti z’omutindo gw’okusiba ezirina ebisaanyizo okukakasa nti vias zijjudde mu bujjuvu n’okuziyiza obululu bwa solder obukweke okuyita ku shielding tape.Arrange random solderability inspection for gold-plated boards. Ebizibu nga zaabu omugonvu n’okukulukuta kwa nickel bwe bimala okuzuulibwa, zibira ebintu ebiriko obuzibu okwewala okuseeyeeya ennyo kwa solder okuva ku kusaasaana kwa solder mu ngeri etaali ya bulijjo.

Twala enkola endala okukendeeza ku kwesigama ku butambi Singa dizayini y’ebintu ekkiriza, ssaako eddagala erirondeddwa ku ngulu, gamba ng’okusiiga zaabu mu kitundu ku paadi zokka n’okulongoosa engalo za zaabu oluvannyuma. Kino kimalawo obwetaavu bw’okuziyiza ku mabbali n’olutambi lwa PTFE era mu musingi kigonjoola ensonga y’okuseeyeeya kwa solder.

Okulonda okutuufu, standardized lamination n'enkola enzijuvu enkolagana okufuga PTFE high-temperature tape bye bisumuluzo ebikulu okumalawo solder creeping. Okulongoosa ebikwata ku nkola kiyinza okulongoosa obulungi amakungula g’okufulumya n’okukendeeza ku nsaasaanya y’okuddamu okukola.

Ebintu eby’ekikugu waggulu biweereddwa Jiangsu Aokai New Materials Technology Co., Ltd.

Bw’oba ​​weetaaga parameters enzijuvu, ensonga z’okusaba n’okugonjoola ebirongooseddwa ku PTFE olugoye olw’ebbugumu eringi, PTFE olugoye olw’ebbugumu eringi, PTFE mesh belt, seamless fusing machine belt, olugoye olusiigiddwa PTFE oludda olumu, omusipi ogutambuza ebbugumu eringi n’olugoye lwa fiberglass, tukusaba otuukirire:

·  Mwami Guo: +86 18944819998

·  Mwami Liu: +86 13705266308

Tunywerera ku ndowooza ya bizinensi ey’obukugu n’obwesimbu, era tuwa eby’okugonjoola ebiyamba amakolero mu kifo kimu n’okulowooza ku mpeereza oluvannyuma lw’okutunda eri bakasitoma b’ensi yonna.
