Kusintha kwa PCB Kupanga: Kapangidwe, Kapangidwe, ndi Mitundu Yambiri

Tsegulani:

Kupanga kwa Flexible PCB kumagwira ntchito yofunika kwambiri pamakampani opanga zamagetsi. Pamene ukadaulo ukupita patsogolo, kufunikira kwa ma PCB osinthika kwakula kwambiri. Pachitsogozo chachikuluchi, tiwona momwe PCB imasinthira, masanjidwe ake, ndi mitundu yakusanjika. Ndikofunika kumvetsetsa mawu otsatirawa:Flexible PCB Manufacturing, Flexible PCB Structure, Flexible PCB Copper Thickness, Flexible PCB Solder Mask, Flexible PCB Layout, Flexible PCB Adhesive Sheet, ndi Flexible PCB Layup Types monga ndizofunika kukhathamiritsa malonda anu.Ndikofunikira.

1. Chidziwitso choyambirira cha kupanga PCB yosinthika:

A. Tanthauzo ndi makhalidwe a bolodi losinthasintha: PCB yosinthika, yomwe imadziwikanso kuti flexible circuit, ndi bolodi losindikizidwa lomwe lingathe kupindika, kupindika, kapena kupindika popanda kusweka. Amapereka maubwino angapo kuposa ma PCB olimba, kuphatikiza kusinthasintha, kupepuka, komanso kulimba. Katunduwa amawapangitsa kukhala oyenera kugwiritsa ntchito zosiyanasiyana, makamaka zomwe zimafunikira zamagetsi zophatikizika komanso zopindika.

B. Mapangidwe a PCB osinthika: Ntchito yomanga ya PCB yosinthika imaphatikizapo kugwiritsa ntchito magawo osinthika. Magawo omwe amagwiritsidwa ntchito kwambiri ndi polyimide ndi poliyesitala, zomwe zimapereka kusinthasintha kofunikira komanso kusungunula komwe kumafunikira ma PCB osinthika. Magawo awa amakumana ndi njira zingapo zopangira monga etching, plating, ndi lamination kuti apange mawonekedwe ofunikira.

C. Kumvetsetsa makulidwe amkuwa mu PCB yosinthika: Makulidwe amkuwa amathandizira kwambiri pakuchita kwa PCB yosinthika. Imatsimikizira kuchuluka kwa kunyamulira kwaposachedwa, kulepheretsa, komanso kusinthasintha kwa PCB. Zosankha zosiyanasiyana za makulidwe amkuwa zitha kupangidwa molingana ndi zofunikira za kapangidwe kake. Mkuwa wokhuthala umapereka mphamvu zonyamulira zamakono komanso umachepetsa kusinthasintha kwa PCB. Kulinganiza koyenera kuyenera kuchitidwa pakati pa zinthu izi kuti zitheke kuchita bwino.

2. Zigawo zazikulu za kupanga PCB zosinthika:

A. Flexible PCB solder mask: Chigoba cha solder ndi chosanjikiza choteteza chomwe chimakwirira mayendedwe opanda mkuwa pa PCB. Zimathandiza kupewa milatho ya solder, dzimbiri, ndi zazifupi zamagetsi panthawi yowotcherera. Flexible PCB imagwiritsa ntchito zida zapadera za solder kuti zitsimikizire kusinthasintha komanso kulimba. Kusintha kwa PCB solder chigoba kusankha ndi ntchito ndondomeko amafuna kuganizira mozama za mapangidwe PCB ndi ntchito yake.

B. Flexible PCB Layout: Mapangidwe opangidwa bwino, osinthika a PCB ndi ofunika kwambiri kuti agwire bwino ntchito ndi kudalirika. Zimakhudza kuyika kwa zigawo, kutsata njira zotsatiridwa, ndi malingaliro a kukhulupirika kwa chizindikiro. Zigawozo ziyenera kuyikidwa m'njira yomwe imalola PCB kupindika ndi kupindika moyenera. Kutsata kuyenera kutsatiridwa kuti muchepetse kupsinjika kwa madera osinthika ndikuwonetsetsa kuti ma siginecha akuyenda bwino. Njira zabwino zopangira masanjidwe osinthika a PCB amaphatikiza kugwiritsa ntchito zokhotakhota, kupewa ngodya zakuthwa, ndikuwonetsetsa kuti pali chilolezo chokwanira pakati pa mayendedwe.

C. Flexible PCB zomatira pepala: An zomatira pepala ntchito kusintha PCB kupanga kulumikiza zigawo zosiyanasiyana pamodzi. Amapereka mphamvu zamakina, kukhazikika, komanso kutsekereza. Pali mitundu yosiyanasiyana ya mapepala omatira omwe alipo, monga mapepala opangidwa ndi acrylic, mapepala opangidwa ndi epoxy, ndi mapepala opangidwa ndi mphira. Kusankhidwa kwa pepala lomatira kumadalira zinthu monga kukana kutentha, zofunikira zosinthika, komanso kugwirizana ndi zipangizo zina. Kusankha pepala lomatira loyenera ndikofunikira kwambiri kuti muwonetsetse kudalirika komanso kulimba kwa PCB yanu yosinthika.

3. Mitundu yowunjika ya PCB yosinthika:

A. Chiyambi cha kusanjika kwa PCB: Kuyika kwa PCB kumatanthawuza makonzedwe a zigawo zosiyanasiyana mu PCB. Pakupanga kosinthika kwa PCB, kusungirako kumatenga gawo lofunikira pakuwonetsetsa kwazizindikiro, kuwongolera kwamphamvu, komanso kasamalidwe kamafuta. Mwa kusankha mosamala ndi kukonza zigawo, okonza akhoza kukhathamiritsa ntchito ya ma PCB osinthika.

B. Common Flexible PCB Layup Types: Pali mitundu yosiyanasiyana ya masanjidwe omwe amagwiritsidwa ntchito popanga PCB yosinthika, kuphatikiza wosanjikiza umodzi, wosanjikiza wapawiri, ndi masinthidwe amitundu yambiri. Mtundu uliwonse wa stacking uli ndi ubwino ndi malire ake. Ma PCB osinthika osanjikiza amodzi ndi njira yosavuta komanso yotsika mtengo, koma ali ndi njira zocheperako. PCB yosinthika yamitundu iwiri imapereka njira zambiri zamawaya ndipo imatha kutengera mapangidwe ovuta kwambiri. Ma PCB osinthika a Multilayer amapereka kusinthasintha kwakukulu, komanso kuwongolera bwino kwa impedance, ndipo amatha kuthandizira kusasunthika kwakukulu. Komabe, ndizovuta komanso zodula kupanga.

Powombetsa mkota:

Mu bukhuli lathunthu, tikufotokoza mbali zonse za kupanga PCB yosinthika, kuphatikizapo zomangamanga, masanjidwe, chigoba cha solder, mapepala omatira, ndi mitundu ya stackup. Kumvetsetsa zinthu zazikuluzikuluzi kumathandizira opanga kukhathamiritsa magwiridwe antchito ndi kudalirika kwa mapangidwe awo osinthika a PCB. Njira ndi matekinoloje ndizofunikira kwambiri pakupanga ma PCB osinthika, ndipo potsatira njira zabwino, opanga amatha kuonetsetsa kuti akupereka zinthu zamtengo wapatali, zodalirika kuti zikwaniritse zosowa zamakampani amagetsi.
