Ihe na-akpata ihe na-akpụ akpụ na ihe ngwọta nke teepu PTFE dị elu

Dị ka onye ọkachamara na-emepụta akwa PTFE dị elu, Jiangsu Aokai New Materials na-ekerịta ụlọ ọrụ ọkachamara. nghọta.In PCB na-ekpo ọkụ ikuku solder larịị, gold plating na immersion gold Filiks, solder na-akpụ akpụ na shielding n'ọnụ nke PTFE elu-okpomọkụ teepu na-tumadi mere site jikọtara mmetụta nke anụ ahụ ọdịda nke teepu na oké usoro gburugburu.

I. Ihe na-ebute ihe na-akpụ akpụ

Edge warping nke PTFE elu-okpomọkụ teepu akpụ gaps N'oge elu okpomọkụ mmepụta, nrapado ike nke teepu ibelata ka okpomọkụ adahade. Mgbe adhesion ezughi oke iji guzogide nrụgide okpomọkụ, akụkụ teepu ahụ ga-adaba ntakịrị wee mepụta oghere capillary, na-ekwe ka ihe na-ere mmiri banye n'ime.

Mmetụta na-emebi emebi na mkpokọ mmiri mmiri na-ere ihe na-achọkarị ịbata n'ebe okpomọkụ dị elu n'anụ ahụ. Mgbe ebe echedoro nọ na oke okpomọkụ, ihe na-ere mmiri na-arịgo elu n'akụkụ oghere nke teepu ahụ n'ụdị wicking. Mmetụta.Na mgbakwunye, teepu PTFE dị oke oke ga-etolite nzọụkwụ na nsọtụ, na-eme ka nchịkọta solder na-etolite dam, nke na-eme ka ihe na-arị arị elu ka njọ.

Ihe na-adabaghị adaba nke teepu okpomọkụ dị elu nke PTFE Ihe ntanye ntanye nke teepu PTFE dị ala na-adịkarị mfe na-asọpụta, mmebi na nrapado nrapado na elu okpomọkụ. Ọ bụghị nanị na ọ na-emebi ihe mgbochi nchebe, kamakwa ọ na-emerụ pads ahụ, na-abawanye ohere nke ịbị ihe na-ere ihe.

Ndị na-emetọ ihe na-agafe teepu PTFE Ọbụlagodi na teepu ahụ adịghị emebi emebi, na-agbawa ma na-efesa beads solder fọdụrụ na PCB vias, ma ọ bụ obere ihe na-ere ere site na vaporization flux n'oge reflow soldering, nwere ike banye ma ọ bụ gafere ebe nchekwa wee bute mmetọ.

Na-ezighị ezi lamination na usoro mgbanwe ọdịda ihichapụ ihe mkpuchi elu ma ọ bụ ezughị ezu ịpị n'oge teepu ngwa ga-ahapụ oghere maka solder penetration.Excessively ngwa ngwa okpomọkụ ịrị elu n'oge reflow soldering sharply enwekwu solder fluidity, na-eme ka ọ dịkwuo mfe imebi site ókè nke PTFE teepu.

Igwe mmiri dị elu nke ebe a na-etinye ọla edo na-eme ka nsogbu ahụ ka njọ n'elu ọla edo-plated na imikpu na-egosipụta ezigbo wettability solder. Ozugbo solder kọntaktị na gold elu, ọ na-agbasa ngwa ngwa tinyere teepu n'ọnụ, dapụtara na a ukwuu ibu na-akpụ akpụ nso karịa OSP na nkịtị na-ekpo ọkụ ikuku solder leveling Filiks.Defects dị ka gold oyi akwa pinholes na nickel corrosion ga-eme ka abnormal local wettability na n'ihu njọ ihu solder na-akpụ akpụ.

II. Ngwọta: Atụmatụ Ngwa nhazi maka teepu PTFE dị elu

Họrọ ruru eru ngwaahịa na standardize lamination ọrụ Nabata elu-edu PTFE elu-okpomọkụ teepu pụrụ iche mepụtara maka PCB elu-okpomọkụ Filiks, na a okpomọkụ na-eguzogide nke 250 ~ 260 ℃ izute ndu-free mmepụta chọrọ.Na-ehicha ihe na-echebe elu nke ọma na isopropanol tupu ngwa iji hụ na zuru kwesịrị ekwesị na-enweghị ihu warping ma ọ bụ gaps. Yiri uwe aka mgbe ị na-arụ ọrụ iji zere mmetọ griiz.

Gbochie bead bead ka ọ ghara imebi site na nchekwa Wepụta usoro tapawa ihe na-agbapụta obere ihe na-ebuli usoro okpomọkụ na-agbagharị. Ikpo ọkụ zuru oke na-ezere vaporization ihe mgbaze na-eme ihe ike ma na-ebelata ohere nke obere cha cha na-agbaji site na mkpuchi teepu.

Mee ka obibi akwụkwọ na njikwa nhicha akụrụngwa dị ike hichaa stencil mgbe ibipụtasịrị PCB ọ bụla 2-3, wee were ọnọdụ ihicha akọrọ + ikuku nhicha iji gbochie tapawa solder splashing na teepu ebe. Na-ewepụ mgbe niile residual solder ntụ ntụ na-ebi akwụkwọ igwe, mounter tracks na fixtures iji kpochapụ nke abụọ mmetọ.

Mkpịsị aka na-abata na usoro àgwà akara ime ka elu maka ihe-agaghị emeli Chọrọ PCB suppliers na-enye ruru eru plugging àgwà asambodo iji hụ n'ụzọ zuru ezu jupụta vias na-egbochi zoro solder chaple si bypassing na shielding teepu.Hazie random solderability nnyocha maka gold-plated mbadamba. Ozugbo a chọtara nsogbu ndị dị ka oyi akwa ọla edo na nickel corrosion, gbochie ngwaahịa ndị na-adịghị mma ka ịzenarị ihe na-akpụ akpụ nke solder na-adịghị mma kpatara.

Nabata usoro ọzọ iji belata ịdabere na teepu Ọ bụrụ na imepụta ngwaahịa nyere ikike, tinye ọgwụgwọ elu dị iche iche, dị ka ịgbanye ọla edo naanị na pads na nhazi mkpịsị aka ọla edo. Nke a na-ewepụ mkpa maka mkpuchi ihu na teepu PTFE ma dozie okwu na-akpụ akpụ nke solder.

Nhọrọ ezi uche dị na ya, lamination ahaziri ahazi na njikwa mmekọrịta zuru oke nke teepu okpomọkụ dị elu nke PTFE bụ isi igodo iji wepụ ihe na-akpụ akpụ. Ịkwalite nkọwa ngwa nwere ike melite mmepụta mmepụta nke ọma ma belata ụgwọ ọrụ ọrụ.
