Kuthetsa zolephera zomwe zachitika pama board okhazikika: Njira ndi machitidwe abwino

Kodi bolodi lanu lokhazikika lomwe limayambitsa mavuto osayembekezereka ndi zida zanu zamagetsi? osadandaula! Cholemba ichi chabulogu chikuwonetsa zolephera zomwe zimachitika nthawi zambiri m'ma board okhazikika ndipo zimapereka njira zothandiza komanso njira zabwino zothetsera mavutowa. Kuchokera kutseguka ndi zazifupi mpaka kuwonongeka kwa soldering ndi kulephera kwa zigawo, timaphimba zonse. Pogwiritsa ntchito njira zoyenera zowunikira zolephera komanso kutsatira malangizo athu akatswiri, mutha kuthana ndi mavutowa ndikubwezeretsa gulu lanu lokhazikika.

Ma board a Rigid-flex circuit akuchulukirachulukira m'makampani opanga zamagetsi chifukwa amatha kupereka kusinthasintha kwakukulu, kudalirika komanso magwiridwe antchito. Ma board awa amaphatikiza magawo osinthika komanso okhazikika kuti athe kupanga mapangidwe ovuta komanso kugwiritsa ntchito bwino malo. Komabe,monga gawo lililonse lamagetsi, matabwa ozungulira okhwima amatha kulephera. Kuti muwonetsetse kudalirika ndi magwiridwe antchito a matabwawa, ndikofunikira kugwiritsa ntchito njira zowunikira zolephera. Mu positi iyi yabulogu, tiwona njira zina zofananira zowunikira kulephera kwa board board.

1.Kuwunika kowoneka

Imodzi mwa njira zoyamba komanso zofunika kwambiri zowunikira kulephera kwa ma board ozungulira okhazikika ndikuwunika kowonera. Kuyang'ana kowoneka kumaphatikizapo kuyang'anitsitsa bwino pa bolodi kuti muwone zizindikiro zilizonse zowonongeka, monga zipsera zosweka, mapepala okwera, kapena zigawo zowonongeka. Njirayi imathandizira kuzindikira zovuta zilizonse zomwe zingayambitse kulephera ndipo zimapereka poyambira pakuwunikanso.

2. Kujambula maikulosikopu ya elekitironi (SEM)

Scanning electron microscopy (SEM) ndi chida champhamvu chomwe chimagwiritsidwa ntchito poyesa kulephera m'mafakitale osiyanasiyana, kuphatikiza zamagetsi zamagetsi. SEM imatha kupanga zithunzi zowoneka bwino zapamtunda ndi zigawo zamagulu ozungulira, kuwulula zambiri za kapangidwe kake, kapangidwe kake ndi zolakwika zilizonse zomwe zilipo. Pofufuza zithunzi za SEM, akatswiri amatha kudziwa chomwe chimayambitsa kulephera, monga ming'alu, delamination kapena mavuto olowa nawo.

3. Kuwunika kwa X-ray

Kuwunika kwa X-ray ndiukadaulo wina womwe umagwiritsidwa ntchito kwambiri pakuwunika kulephera kwa ma board ozungulira okhazikika. Kujambula kwa X-ray kumathandizira akatswiri kusanthula mawonekedwe amkati a matabwa ozungulira, kuzindikira zolakwika zobisika ndikuzindikira mtundu wa zida zogulitsira. Njira yosawononga iyi yoyesera imatha kupereka chidziwitso pazomwe zimayambitsa kulephera, monga ma voids, kusalumikizana bwino kapena kuwotcherera kosakwanira.

4. Kujambula kwa kutentha

Thermal imaging, yomwe imadziwikanso kuti infrared thermography, ndiukadaulo womwe umazindikira ndikuwona kusintha kwa kutentha. Pogwira kugawa kwa kutentha pama board ozungulira okhazikika, mainjiniya amatha kuzindikira malo otentha, zida zotenthetsera kapena matenthedwe achilendo. Kujambula kwa kutentha kumakhala kothandiza kwambiri pozindikira mavuto omwe amayamba chifukwa cha kuchulukirachulukira kwamagetsi, kuwongolera bwino kwa kutentha, kapena zigawo zosagwirizana.

5. Mayeso amagetsi

Kuyesa kwamagetsi kumatenga gawo lofunikira pakuwunika kulephera kwa ma board ozungulira okhazikika. Njirayi imaphatikizapo kuyeza magawo amagetsi monga kukana, capacitance ndi voteji pazigawo zosiyanasiyana pa bolodi la dera. Poyerekeza miyeso ndi zomwe zikuyembekezeka, mainjiniya amatha kuzindikira zida zolakwika, zazifupi, zotsegula, kapena zovuta zina zamagetsi.

6. Kusanthula kwapang'onopang'ono

Kusanthula kwapang'onopang'ono kumaphatikizapo kudula ndikuwunika zitsanzo zama board ozungulira okhazikika. Ukadaulowu umathandizira mainjiniya kuti azitha kuwona zigawo zamkati, kuzindikira zomwe zingatheke kapena kupatukana pakati pa zigawo, ndikuwunikanso mtundu wa zida zopukutira ndi gawo lapansi. Kusanthula kwapang'onopang'ono kumapereka chidziwitso chozama cha kapangidwe ka komiti yoyang'anira dera ndikuthandizira kuzindikira zolakwika zopanga kapena kupanga.

7. Kulephera Mode ndi Kusanthula Zotsatira (FMEA)

Failure Mode and Effects Analysis (FMEA) ndi njira yowunikira ndikuyika patsogolo zolephera zomwe zingachitike mkati mwadongosolo. Poganizira njira zosiyanasiyana zolepherera, zomwe zimayambitsa, komanso momwe magwiridwe antchito amagwirira ntchito, mainjiniya amatha kupanga njira zochepetsera ndikuwongolera mapangidwe, kupanga, kapena kuyesa njira kuti apewe kulephera kwamtsogolo.

Powombetsa mkota

Njira zowunikira zolephera zomwe zafotokozedwa patsamba lino labulogu zimapereka chidziwitso chofunikira pakuzindikiritsa ndi kuthetsa zovuta zama board ozungulira. Kaya kudzera mu kuyang'ana kowoneka, kuyang'ana ma electron microscopy, kuyendera ma X-ray, kujambula kwa kutentha, kuyesa magetsi, kusanthula magawo, kapena kulephera ndi kusanthula zotsatira; njira iliyonse imathandizira kumvetsetsa bwino chomwe chimayambitsa kulephera. Pogwiritsa ntchito matekinolojewa, opanga ndi mainjiniya amatha kukulitsa kudalirika, magwiridwe antchito ndi magwiridwe antchito a ma board ozungulira okhazikika, kuwonetsetsa kuti akuchita bwino m'dziko lamagetsi lomwe likusintha.
