Kuchepa kwa kukula ndi mawonekedwe a matabwa osinthika osinthika

Mu positi iyi yabulogu, tiwona kukula ndi malire a ma board osinthika komanso momwe zoperewerazi zimakhudzira zosankha zamapangidwe.

Ma board ozungulira osinthika, omwe amadziwikanso kuti ma PCB osinthika, asintha makampani opanga zamagetsi ndi luso lawo lapadera lopinda ndikusintha mawonekedwe osiyanasiyana. Ma board osinthikawa amatsegula mwayi watsopano wopanga zida zazing'ono, zopepuka, komanso zosunthika kwambiri. Komabe, monga momwe zilili ndi ukadaulo wina uliwonse, pali zoletsa zina zomwe ziyenera kuganiziridwa mukamagwiritsa ntchito ma board osinthika.

Zoletsa za kukula kwa matabwa osinthasintha:

matabwa osinthika dera ndi ubwino yaikulu pa PCBs okhwima pankhani kukula. Kusinthasintha kwawo kumapangitsa kuti pakhale mapangidwe ophatikizika komanso kuthekera kokwanira mumipata yothina. Komabe, pali zoletsa zina za kukula zomwe muyenera kukumbukira.

1. M'lifupi ndi kutalika:M'lifupi ndi kutalika kwa bolodi losinthasintha la dera limatsimikiziridwa ndi kukula kwa gawo lapansi lomwe limagwiritsidwa ntchito. Zida zodziwika bwino monga polyimide kapena Mylar nthawi zambiri zimabwera mumitundu yofananira, ndikuchepetsa m'lifupi mwake komanso kutalika kwa bolodi lozungulira. Miyeso yokhazikika iyi imatha kusiyanasiyana kutengera wopanga, koma nthawi zambiri imachokera mainchesi angapo mpaka mapazi angapo.

2. Makulidwe:Ma board flexible circuit nthawi zambiri amakhala owonda kuposa matabwa olimba. Kukula kwa PCB yosinthika kumatsimikiziridwa ndi gawo lapansi ndi makulidwe a zigawo zina zowonjezera, monga mikwingwirima yamkuwa kapena chigoba cha solder. Zigawozi zimawonjezera makulidwe onse a bolodi ndipo ziyenera kuganiziridwa panthawi yojambula. Ma board a Thinner amapereka kusinthasintha koma amatha kuwonongeka.

Zoletsa za mawonekedwe a matabwa osinthasintha:

Ma board ozungulira osinthika amakhala osinthika kwambiri. Kuthekera kwawo kupindika ndikugwirizana ndi mitundu yosiyanasiyana ya ma geometri kumathandizira kupanga kwatsopano. Komabe, pali zopinga zina za mawonekedwe zomwe ziyenera kuganiziridwa.

1. Kupindika kozungulira:Ma radius opindika ndi chinthu chofunikira kuganizira popanga ma board osinthasintha. Zimatanthawuza utali wocheperako wopindika womwe bolodi lozungulira limatha kupirira popanda kuwononga zingwe kapena zigawo. Utali wopindika umatsimikiziridwa ndi makulidwe ndi katundu wa gawo lapansi. Nthawi zambiri, kuchepera kwa bolodi, kumachepetsanso utali wopindika. Zolemba za wopanga kapena malangizo akuyenera kufufuzidwa nthawi zonse kuwonetsetsa kuti malire a board sadutsa.

2. Mawonekedwe ovuta:Ngakhale ma board osinthika amatha kupindika ndi kupindika, kupanga mawonekedwe ovuta a 3D kumatha kukhala kovuta. Ngodya zakuthwa, zopindika zovuta, kapena zokhotakhota zambiri zimatha kutsindika za bolodi ndikusokoneza kukhulupirika kwake. Okonza ayenera kuganizira mozama zofooka za zinthuzo ndikuonetsetsa kuti mawonekedwe omwe akufunidwa angathe kukwaniritsidwa popanda kuika pangozi.

Konzani mapangidwe ndi kusinthasintha m'malingaliro a matabwa osinthasintha:

Ngakhale kuti ali ndi malire, matabwa osinthasintha osinthasintha amapereka ubwino wambiri. Kuti muwonetsetse kuti mapangidwe abwino apangidwe, kukula kwake ndi zopinga za mawonekedwe ziyenera kuganiziridwa kuyambira pachiyambi. Nawa maupangiri okometsera mapangidwe anu osinthika a PCB:

1. Fufuzani ndi wopanga:Wopanga aliyense akhoza kukhala ndi kukula kosiyana pang'ono ndi mawonekedwe ake. Ndikofunikira kuti mufunsane ndi wopanga zomwe mwasankha koyambirira kwa kapangidwe kake kuti mumvetsetse zolephera zawo komanso kapangidwe koyenera.

2. Gwiritsani ntchito zida zoyeserera:Pali zida zosiyanasiyana zofananira zomwe zingathandize kuwunika momwe ma board oyendera amasinthira pamapindika osiyanasiyana. Zida izi zitha kuthandizira kudziwa bend radii, kupsinjika kwa kupsinjika ndi zomwe zingalephereke, kulola opanga kupanga zisankho zanzeru.

3. Kukonzekera kusinthasintha:Popanga ndi ma PCB osinthika, ndikwanzeru kuphatikizira zinthu zina zamapangidwe kuti zithandizire kusinthasintha. Mwachitsanzo, kupereka mipata yokwanira pakati pa zigawo ndi zizindikiro kungapangitse kuti bolodi ikhale yosavuta kuti ipirire popanda kuwononga kapena kuchepetsa.

Pomaliza, pomwe matabwa osinthika osinthika amapereka zabwino zambiri, ndikofunikira kukumbukira kukula kwawo ndi malire awo.Pomvetsetsa ndikugwira ntchito mkati mwa zopingazi, okonza amatha kupanga zipangizo zamagetsi zamakono komanso zodalirika. Ndi kukonzekera koyenera, kukambirana ndi opanga, ndi kugwiritsa ntchito zida zofananira, mapangidwe osinthika a PCB amatha kukankhira malire a kukula ndi mawonekedwe kuti apange zinthu zamagetsi zogwira mtima komanso zapamwamba.
