Zochepa mu kukula kwa okhwima flex PCB bolodi

Ma board a Rigid-flex (mabokosi osindikizidwa) asintha momwe zida zamagetsi zimapangidwira ndikupangidwira. Kukhoza kwawo kuphatikiza ubwino wa mabwalo okhwima ndi osinthasintha kwawapangitsa kukhala otchuka kwambiri m'mafakitale osiyanasiyana. Komabe, monga ukadaulo uliwonse, rigid-flex ili ndi malire ake malinga ndi kukula.

Ubwino umodzi wofunikira kwambiri wa mapanelo olimba osinthika ndikutha kupindika kapena kupindika kuti agwirizane ndi mipata yolumikizana komanso yosawoneka bwino.Kusinthasintha kumeneku kumathandizira opanga kuti aphatikize ma PCB pazida zomwe sizikhala ndi malo monga mafoni a m'manja, zovala, kapena zoyika zachipatala. Ngakhale kusinthasintha kumeneku kumapereka ufulu wambiri pakupanga, kumabwera ndi zolepheretsa kukula kwake.

Kukula kwa PCB yokhazikika-yosinthika kumatsimikiziridwa ndi zinthu zosiyanasiyana, kuphatikizapo kupanga, kuchuluka kwa zigawo, ndi kachulukidwe kagawo.Kapangidwe ka ma PCB olimba osinthika kumaphatikizapo kulumikiza magawo olimba komanso osinthika, omwe amaphatikiza zigawo zingapo zamkuwa, zotchingira ndi zomatira. Chigawo chilichonse chowonjezera chimawonjezera zovuta komanso mtengo wakupanga.

Pamene chiwerengero cha zigawo chikuwonjezeka, makulidwe onse a PCB amawonjezeka, kuchepetsa kukula kochepa komwe kungatheke. Kumbali ina, kuchepetsa chiwerengero cha zigawo kumathandiza kuchepetsa makulidwe onse koma kungakhudze magwiridwe antchito kapena zovuta za mapangidwe.

Kachulukidwe kazinthu kumakhalanso ndi gawo lofunikira pakuzindikiritsa malire a kukula kwa ma PCB okhazikika.Apamwamba chigawo kachulukidwe amafuna kuda zambiri, vias, ndi PAD danga, potero kuwonjezera wonse PCB kukula. Kuchulukitsa kukula kwa PCB sikoyenera nthawi zonse, makamaka pazida zazing'ono zamagetsi pomwe malo amalipira.

Chinanso chomwe chimalepheretsa kukula kwa matabwa olimba ndi kupezeka kwa zida zopangira.Opanga PCB ali ndi malire pa kukula kwake komwe angapange. Miyezo ingasiyane ndi wopanga, koma nthawi zambiri imayambira mainchesi angapo mpaka mapazi angapo, kutengera luso la chipangizocho. Makulidwe akulu a PCB amafunikira zida zapadera ndipo atha kukhala ndi ndalama zambiri zopangira.

Zofooka zaukadaulo zimaganiziridwanso zikafika pakukula ma PCB okhwima.Kupita patsogolo kwaukadaulo kwapangitsa zida zamagetsi kukhala zazing'ono komanso zophatikizika. Komabe, zigawozi zikhoza kukhala ndi malire awo ponena za kulongedza wandiweyani ndi kutaya kutentha. Kuchepetsa miyeso ya PCB yokhazikika kwambiri kungayambitse zovuta zowongolera kutentha ndikusokoneza kudalirika konse ndi magwiridwe antchito a chipangizo chamagetsi.

Ngakhale pali malire a kukula kwa matabwa olimba-flex, malirewa adzapitirira kukankhidwa pamene teknoloji ikupita patsogolo.Kuchepa kwa kukula kumathetsedwa pang'onopang'ono pamene njira zopangira zinthu zimakhala zapamwamba kwambiri komanso zida zapadera zikupezeka mosavuta. Kuphatikiza apo, kupita patsogolo kwa gawo la miniaturization ndiukadaulo wowongolera kutentha kwapangitsa kuti zitheke kugwiritsa ntchito zida zing'onozing'ono, zamphamvu kwambiri zamagetsi pogwiritsa ntchito matabwa olimba a PCB.

Powombetsa mkota:

Rigid-flex PCB imaphatikiza ubwino wa mabwalo okhwima komanso osinthika, kupereka kusinthasintha kwakukulu. Komabe, ma PCB awa ali ndi malire malinga ndi kukula kwake. Zinthu monga njira zopangira, kachulukidwe kagawo, kuthekera kwa zida ndi zovuta zaukadaulo zimagwira ntchito yofunika kwambiri pakuzindikira kukula kwakukulu komwe kungatheke. Ngakhale zili zolepheretsa izi, kupita patsogolo kwaukadaulo ndi njira zopangira zikupitilira malire a ma board osindikizidwa okhazikika.
