Kupanga kwamagetsi kwama board osindikizidwa (omwe pano amatchedwa PCB) malonda akhala akugwiritsidwa ntchito kuyambira 1948 ndipo adayamba kutuluka ndikugwiritsidwa ntchito kwambiri m’ma 1950. Makampani achikhalidwe cha PCB ndimakampani ogwira ntchito mwakhama ndipo luso lawo limakhala locheperako kuposa la makampani opanga semiconductor. Kuyambira koyambirira kwa 2000s, makampani opanga semiconductor asunthira pang’onopang’ono kuchoka ku US ndi Japan kupita ku Taiwan ndi China. Pakadali pano, China yakhala yopanga ma PCB padziko lonse lapansi, ndikuwerengera zoposa 60% zama PCB padziko lonse lapansi.

Zida zamankhwala:

Kupita patsogolo kwamasiku ano kwasayansi yazachipatala kumachitika chifukwa chakukula kwamsika kwamagetsi. Zipangizo zambiri zamankhwala (mwachitsanzo, mamita a pH, masensa othamanga pamtima, kuyeza kutentha, ELECTROcardiogram / EEG, zida za MRI, ma X-ray, ma scan a CT, zida zamagazi, zida zoyezera magazi m’magazi, ma incubator, zida zama microbiological, ndi zina zambiri) ndi ma pcBS -zogwiritsidwa ntchito payekha. Ma PCBS awa nthawi zambiri amakhala ophatikizika ndipo amakhala ndi ma coefficients ang’onoang’ono. Masensa osakanikirana amatanthauza kuyika zigawo zing’onozing’ono za SMT mumiyeso yaying’ono ya PCB. Zipangizo zamankhwala izi ndizazing’ono, zosavuta kunyamula, zopepuka komanso zosavuta kugwiritsa ntchito.

Zida zamakampani.

PCBS imagwiritsidwanso ntchito popanga, mafakitale ndi mbewu zoyandikana. Makampaniwa ali ndi makina amagetsi othamangitsidwa ndi ma circuits ogwiritsa ntchito kwambiri omwe amafunikira zamakono. Kuti muchite izi, gawo lalikulu la PCB lokutidwa ndi mkuwa wambiri, womwe, mosiyana ndi ma PCBS ovuta, amakhala ndi ma amperes 100. Izi ndizofunikira kwambiri pakugwiritsa ntchito monga kuwotcherera kwa arc, oyendetsa magalimoto akuluakulu a servo, ma charger a lead-acid, kusamveka kwa nsalu za thonje zamagulu ankhondo ndi zovala.

Kuwala

Pakuwunikira, dziko lapansi likupita ku njira zamagetsi. These halogen bulbs are rare now, but now we see LED lights and high-intensity leds around. Ma ledi ang’ono awa amapereka kuwala kwambiri ndipo amaikidwa pa PCBS zotengera zotayidwa. Aluminium imakhala ndi malo otengera kutentha ndikuyatsira mlengalenga. Chifukwa chake, chifukwa cha mphamvu yayikulu, ma PCBS a aluminium awa amagwiritsidwa ntchito kwambiri m’mayendedwe amagetsi a LED apakatikati komanso amphamvu ma circuits a LED.

Magalimoto ndi malo osungira

Another application of PCBS is in the automotive and aerospace industries. Chofala apa ndikubwezeretsanso ndege kapena magalimoto. Chifukwa chake, kuti athetse kugwedezeka kwamphamvu kwambiri, PCB imasintha.

Chifukwa chake, gwiritsani ntchito PCB yotchedwa Flex PCB. PCB yosinthayo imatha kupilira kugwedera kwakukulu komanso kulemera kopepuka, motero kumachepetsa kulemera konse kwa chombo. Ma PCBS osinthasinthawa amathanso kusinthidwa m’malo opapatiza, amenenso ndi mwayi waukulu. PCBS zosinthazi zimakhala zolumikizira, polumikizira, ndipo zimatha kusonkhanitsidwa m’malo ophatikizika, monga kumbuyo kwa mapanelo, pansi pamadeshodi, ndi zina zambiri. Kuphatikiza kwa PCBS yolimba komanso yosinthasintha itha kugwiritsidwanso ntchito (PCBS okhwima).

Kuchokera pakugawana mafakitale ogwiritsa ntchito, zamagetsi zamagetsi zimawerengedwa kwambiri, mpaka 39%; Makompyuta anali ndi 22%; Kulankhulana 14%; Industrial controls and medical equipment accounted for 14 per cent; Automotive electronics accounted for 6%. Chitetezo ndi malo othamangitsira malo amawerengera 5%, malo opangira zida zamagetsi ndi zamankhwala ndi zina ndizofunikira kwambiri pakulondola kwa PCB.

PCB imagwiritsidwa ntchito kwambiri chifukwa ili ndi zabwino zambiri, zomwe zitha kufotokozedwa mwachidule motere.

1. Kutalika kwambiri.

Ndikusintha kophatikizika kwa makina ophatikizira ndi ukadaulo wopangira, ma PCBS othamanga kwambiri amatha kupangidwa.

2. Kudalirika kwambiri.

Kudzera mndandanda wa zowunikira, mayeso ndi ukalamba, PCB imatha kutsimikizika kuti izigwira ntchito mokhulupirika kwanthawi yayitali.

3. Kukhazikika.

Kwa mitundu yonse ya magwiridwe antchito a PCB (zamagetsi, zakuthupi, zamankhwala, zamakina, ndi zina zambiri), zitha kukhazikitsidwa mwanjira yakapangidwe, kukhazikika ndi njira zina kuti mukwaniritse nthawi yosanja ya board ndiyosavuta, yokwanira.

4. Wogwira ntchito.

Kudzera kasamalidwe amakono, kukhazikika, kuchuluka (kuchuluka), makina osinthira ndi zina zitha kuchitika kuti zitsimikizire kuti zinthu zikuyenda bwino.

Kuyesedwa.

Njira yoyeserera yokwanira, miyezo yoyesera, zida zosiyanasiyana zoyeserera ndi zida zakhazikitsidwa kuti ziyesedwe ndikuzindikira zinthu za PCB kuti zigwirizane ndi moyo wautumiki.

6. Kusonkhana.

Mankhwala PCB osati atsogolere yovomerezeka khamu la zigawo zosiyanasiyana, komanso atsogolere zodziwikiratu ndi kuŵeta.

Nthawi yomweyo, PCBS ndi magawo am’magawo azinthu zosiyanasiyana atha kusonkhanitsidwa m’magawo akulu, makina, kapena makina athunthu.

7. Kusamalira.

Zogulitsa za PCB ndi misonkhano yamagawo zimakhala zoyimitsidwa chifukwa zimapangidwa ndikupanga pamlingo woyenera.

Mwanjira imeneyi, dongosololi likalephera, limatha kusinthidwa mwachangu, mosavuta komanso mosinthika, ndikubwezeretsanso mwachangu ntchito zantchitoyo.
