Zida zochepetsera kugwedezeka mu PCB yosinthika ya 14-wosanjikiza zidasankhidwa kuti ziteteze ku kugwedezeka kwamakina.

Momwe mungasankhire zida zochepetsera ndi kugwedera zoyenera 14-wosanjikiza flex pcb kuti mupewe kugwedezeka kwamakina ndi kukhudzidwa kwa board board?

Tsegulani:

As kupita patsogolo kwaukadaulo ndi zida zamagetsi zikupitilizabe kukula, kufunikira kwa kugwedezeka ndi chitetezo chodzidzimutsa kwa matabwa ozungulira chawonjezeka kwambiri. PCB yolimba komanso yodalirika ya 14-layer flexible PCB ndiyofunikira pamagwiritsidwe osiyanasiyana, ndipo kuti mukwaniritse izi, kusankha zida zoyenera zonyowetsa ndi kunjenjemera ndikofunikira. Mu blog iyi, tiwona zinthu zomwe tiyenera kuziganizira posankha zida zotere komanso momwe zimatetezera ku zotsatira zoyipa za kugwedezeka kwamakina ndi kugwedezeka pama board ozungulira.

Kufunika kwa zinthu zochepetsera komanso zochepetsera kugwedezeka:

Kugwedezeka kwamakina ndi kugwedezeka kumatha kukhala ndi zotsatirapo zazikulu pa magwiridwe antchito ndi kudalirika kwa 14-wosanjikiza PCB yosinthika. Kugwedezeka uku kumatha kukakamiza zigawo, kupangitsa kuti ma solder athyoke, akabudula amagetsi, kapena kulephera kwathunthu kwa board board. Kuonetsetsa moyo wautali wa PCB ndi magwiridwe antchito, ndikofunikira kusankha zida zoyenera zonyowetsa zomwe zitha kuyamwa kapena kuwononga mphamvu zomwe zimapangidwa ndi kugwedezeka ndi kugwedezeka.

Zofunika kuziganizira:

1. Kusiyanasiyana:
Chinthu choyamba choyenera kuganizira ndi kuchuluka kwa ma vibrations omwe PCB imawululidwa. Zida zosiyanasiyana zimagwira bwino kugwedezeka kwa ma frequency osiyanasiyana. Chifukwa chake, ndikofunikira kudziwa kuchuluka kwamphamvu ndikusankha zinthu zonyowa moyenera. Kusanthula mozama kwa kugwedezeka komwe kukuyembekezeka kumathandizira kusankha zinthu zolondola zomwe zingachepetse kugwedezeka.

2. Zakuthupi:
Zida zosiyanasiyana zimakhala ndi zinthu zosiyanasiyana zochepetsera, ndipo ndikofunikira kusankha zida zomwe zimakwaniritsa zofunikira za PCB yosinthika ya 14-wosanjikiza. Zina mwazinthu zomwe zimadziwika kuti zimanyowetsa zimaphatikizira ma elastomers, ma polima a viscoelastic, thovu, ndi ma composite. Chilichonse chili ndi mawonekedwe akeake, monga kuuma, viscoelasticity, ndi mphamvu zoyamwa mphamvu. Kumvetsetsa izi komanso momwe zimakhudzira kuthekera kwa kugwedera ndikofunikira kuti mupange chisankho choyenera.

3. Zoganizira zachilengedwe:
Malo ogwirira ntchito amakhala ndi gawo lofunikira pakusankha zinthu zoyenera zonyowa. Zinthu monga kusintha kwa kutentha, kuchuluka kwa chinyezi komanso kukhudzana ndi mankhwala zimatha kukhudza magwiridwe antchito a zinthu zonyowa. Ndikofunikira kuwunika momwe chilengedwe chilili momwe 14-layer flex PCB idzagwirira ntchito ndikusankha zinthu zomwe zingapirire izi popanda kusokoneza kuthekera kwake konyowa.

4. Kusinthasintha ndi kuyanjana:
Popeza tikuchita ndi PCB yosinthika ya 14-wosanjikiza, kusankha kwa zinthu zonyowa kuyeneranso kuganizira za kusinthasintha ndi kugwirizana kwa gawo lapansi losinthika. Zinthuzo siziyenera kulepheretsa kusinthasintha kwa PCB ndipo ziyenera kumamatira pamwamba pake. Ndibwino kuti tichite kuyesa kofananira kuonetsetsa kuti zinthu zomwe zasankhidwa sizikusokoneza magwiridwe antchito a PCB yosinthika.

Pewani kugwedezeka kwamakina pama board ozungulira:

1. Njira zolondola zoyikira:
Kuphatikiza pa kugwiritsa ntchito zida zonyowa, njira zoyenera zoyikira ndizofunikira kuti tipewe kugwedezeka kwamakina pa bolodi yozungulira. Kuyika mosamala PCB kumalo ake otsekera kapena oletsa kugwedezeka kumathandizira kuchepetsa kufalikira kwa kugwedezeka kwa bolodi. Zothandizira zamakina zopangidwa bwino zimatsimikizira kuti PCB imakhalabe yokhazikika ngakhale ikugwedezeka kwakunja kapena kugwedezeka.

2. Kusankha zinthu:
Kusankha zida zolimba, zodalirika zomwe zimatha kupirira kugwedezeka ndi kugwedezeka ndi chinthu china chofunikira. Zigawo zokhala ndi kugwedezeka kokhazikika komanso kukana kugwedezeka, monga zolumikizira zolimbitsa thupi kapena elastomeric encapsulation, zitha kupititsa patsogolo kulimba kwa board board. Ndikofunikira kuti mugwire ntchito ndi omwe akukupatsirani magawo kuti musankhe zida zolimba zomwe zimayenera kugwedezeka.

3. Kuyesa mwamphamvu:
Pomaliza, ndikofunikira kuyesa mwamphamvu PCB yosinthika ya 14-wosanjikiza pagawo ndi magawo adongosolo kuti muwonetsetse kuti imatha kupirira kugwedezeka ndi kugwedezeka. Kuwonetsa ma board ozungulira kumayendedwe oyimira makina ogwedezeka ndikuwunika momwe amagwirira ntchito ndikofunikira kuti muwonetsetse kuti zida zochepetsera zomwe zasankhidwa ndi zochepetsera kugwedezeka ndizofunikira.

Pomaliza:

Kusankha zipangizo zoyenera zochepetsera ndi kuchepetsa kugwedezeka ndikofunikira kuti muteteze kugwedezeka kwa makina pa PCB yosinthika ya 14-layer. Kuganizira zinthu monga kuchuluka kwa ma frequency, zinthu zakuthupi, momwe chilengedwe chimakhalira, kusinthasintha komanso kuyanjana kungathandize kupanga chisankho mwanzeru.Kuphatikiza apo, kugwiritsa ntchito njira zoyikira zolondola, kusankha zida zolimba, ndikuyesa mozama ndi njira zofunika kuwonetsetsa kuti bolodiyo ikhazikika komanso yodalirika motsutsana ndi kugwedezeka kwa makina ndi kugwedezeka. Pochita izi, magwiridwe antchito ndi moyo wautumiki wa PCB zitha kutsimikizika, potero kuwongolera magwiridwe antchito onse a chipangizo chamagetsi.
