Kusiyana kwakukulu pakati pa matabwa a mbali imodzi ndi mbali ziwiri zolimba-flex

Chiyambi:

M'nkhaniyi, tiwona mbali zazikuluzikulu, ubwino ndi kuipa kwa PCB za mbali imodzi ndi ziwiri zolimba-flex.

Ngati muli mumakampani amagetsi, mwina mwakumanapo ndi mawu akuti single sided and double sided rigid-flex board. Ma board ozungulirawa amagwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana zamagetsi, koma kodi mukudziwa kusiyana kwakukulu pakati pawo?

Tisanalowe mwatsatanetsatane, tiyeni timvetsetse chomwe PCB yokhazikika-yokhazikika ndi. Rigid-flex ndi mtundu wosakanizidwa wama board ozungulira omwe amaphatikiza kusinthasintha kwa ma board osinthika komanso okhazikika osindikizidwa. Ma board awa amakhala ndi zigawo zingapo za gawo lapansi losinthika lomwe limamangiriridwa ku matabwa amodzi kapena angapo olimba. Kuphatikiza kusinthasintha ndi kusasunthika kumathandizira mapangidwe ovuta amitundu itatu, kupanga ma PCB olimba osinthika kukhala abwino kwa mapulogalamu omwe malo ali ochepa.

Tsopano, tiyeni tikambirane za kusiyana kwa matabwa a mbali imodzi ndi mbali ziwiri zolimba zomangira:

1. Kapangidwe:
PCB yokhazikika kumbali imodzi imakhala ndi gawo limodzi lokhazikika lokhazikika pa bolodi limodzi lolimba. Izi zikutanthauza kuti dera lilipo mbali imodzi yokha ya gawo lapansi losinthika. Kumbali inayi, PCB yokhala ndi mbali ziwiri yokhazikika yokhazikika imakhala ndi zigawo ziwiri za magawo osinthika omwe amamangiriridwa mbali zonse za bolodi lolimba. Izi zimathandiza kuti gawo lapansi losinthika likhale ndi zozungulira mbali zonse ziwiri, ndikuwonjezera kuchulukana kwa zigawo zomwe zitha kukhalamo.

2. Kuyika kwazinthu:
Popeza pali zozungulira mbali imodzi yokha, PCB yokhala ndi mbali imodzi yokhayokha imapereka malo ochepa oyikapo. Izi zitha kukhala malire popanga mabwalo ovuta okhala ndi zigawo zambiri. Mbali ziwiri zolimba-flex matabwa osindikizira osindikizira, kumbali ina, amalola kugwiritsa ntchito bwino malo mwa kuika zigawo mbali zonse za gawo lapansi losinthika.

3. Kusinthasintha:
Ngakhale ma PCB a mbali imodzi komanso mbali ziwiri olimba-osinthasintha amapereka kusinthasintha, mitundu ya mbali imodzi nthawi zambiri imapereka kusinthasintha kwakukulu chifukwa cha kapangidwe kake kosavuta. Kusinthasintha kumeneku kumawapangitsa kukhala oyenera kugwiritsa ntchito zomwe zimafunika kupindika mobwerezabwereza, monga zida zovala kapena zinthu zomwe zimasunthidwa pafupipafupi. Mabokosi osindikizira a mbali ziwiri olimba-flex, akadali osinthika, amatha kukhala owuma pang'ono chifukwa cha kuwonjezereka kwa gawo lachiwiri la gawo lapansi losinthika.

4. Kuvuta Kupanga:
Poyerekeza ndi PCB yokhala ndi mbali ziwiri, PCB yokhala ndi mbali imodzi yokhayokha ndiyosavuta kupanga. Kusapezeka kwa ma circuitry kumbali imodzi kumachepetsa zovuta zomwe zimachitika pakupanga. Ma PCB okhala ndi mbali ziwiri okhazikika amakhala ndi zozungulira mbali zonse ziwiri ndipo amafunikira kuwongolera bwino komanso njira zina zopangira kuti zitsimikizire kulumikizana koyenera kwa magetsi pakati pa zigawo.

5. Mtengo:
Kuchokera pamawonekedwe amtengo, matabwa a mbali imodzi olimba-osinthasintha nthawi zambiri amakhala otchipa kuposa ma board a mbali ziwiri olimba. Zomangamanga zosavuta ndi njira zopangira zimathandizira kuchepetsa mtengo wa mapangidwe a mbali imodzi. Komabe, zofunikira zenizeni za ntchitoyo ziyenera kuganiziridwa, monga nthawi zina ubwino woperekedwa ndi mapangidwe a mbali ziwiri ukhoza kupitirira mtengo wowonjezera.

6.Design kusinthasintha:
Pankhani ya kusinthasintha kwapangidwe, ma PCB a mbali imodzi komanso mbali ziwiri zolimba-flex ali ndi ubwino. Komabe, ma PCB okhala ndi mbali ziwiri olimba-osinthika amapereka mwayi wowonjezera chifukwa mabwalo amapezeka mbali zonse. Izi zimapangitsa kuti pakhale zolumikizana zovuta kwambiri, kukhulupirika kwazizindikiro komanso kuwongolera bwino kwamafuta.

Powombetsa mkota

Kusiyanitsa kwakukulu pakati pa matabwa a mbali imodzi ndi mbali ziwiri zolimba-zokhazikika ndizopangidwe, mphamvu zoyika zigawo, kusinthasintha, kupanga zovuta, mtengo ndi kusinthasintha kwa mapangidwe. Ma PCB olimba a mbali imodzi amapereka kuphweka komanso ubwino wamtengo wapatali, pamene ma PCB a mbali ziwiri olimba osinthasintha amapereka kachulukidwe kagawo kakang'ono, zotheka kamangidwe kabwino, komanso kuthekera kopititsa patsogolo kukhulupirika kwa chizindikiro ndi kayendetsedwe ka kutentha. Kumvetsetsa kusiyana kwakukulu kumeneku kudzakuthandizani kupanga chisankho chodziwitsidwa posankha PCB yoyenera pa pulogalamu yanu yamagetsi.
