Vibration-damping zvinhu mu14-layer inochinjika PCB yakasarudzwa kuchengetedza kubva kumagetsi kuvhunduka.

Nzira yekusarudza sei damping uye vibration kuderedza zvinhu zvakakodzera 14-layer flex pcb kudzivirira kukanganisa kwema mechanical vibration uye kukanganisa pabhodhi redunhu?

suma:

As tekinoroji kufambira mberi uye zvigadzirwa zvemagetsi zvinoramba zvichiderera muhukuru, kukosha kwekuzunguza uye kuchengetedzwa kwekuvhunduka kwemapuranga edunhu kwakawedzera zvakanyanya. Iyo yakasimba uye yakavimbika 14-layer inochinjika PCB yakakosha kune akasiyana maapplication, uye kuti uite izvi, kusarudza iyo chaiyo yekunyorovesa uye inonyudza-kunyudza zvinhu kwakakosha. Mune ino blog, isu tichatarisa zvinhu zvekufunga nezvazvo pakusarudza zvinhu zvakadaro uye kuti vanodzivirira sei kubva kune inokuvadza mhedzisiro yemagetsi vibration uye kuvhunduka pamabhodhi edunhu.

Kukosha kwekunyorovesa uye kudengenyeka-kudzikisa zvinhu:

Mechanical vibration uye kuvhunduka kunogona kuve nemhedzisiro yakakomba pakushanda uye kuvimbika kwe14-layer inochinjika PCB. Aya mavibrations anogona kusimbisa zvikamu, zvichiita kuti majoini ekutengesa atyoke, zvipfupi zvemagetsi, kana kutadza kuzara kwebhodhi redunhu. Kuti uve nechokwadi chekugara kwenguva refu kwePCB uye kuita, zvakakosha kuti usarudze zvinhu zvinonyorovesa zvakakodzera zvinogona kutora kana kubvisa simba rinogadzirwa nekuzunguza uye kuvhunduka.

Zvinhu zvekufunga nezvazvo:

1. Frequency range:
Chinhu chekutanga chekufunga nezve frequency renji yevibrations iyo PCB inoburitswa. Zvishandiso zvakasiyana zvakanaka pakubata vibrations mune chaiyo frequency renji. Naizvozvo, zvakakosha kuona iyo inotungamira frequency uye sarudza iyo inonyorovesa zvinhu zvinoenderana. Kunyatsoongorora kweiyo inotarisirwa vibration spectrum ichabatsira kusarudza iyo chaiyo zvinhu izvo zvinonyatso dzikamisa kudedera.

2. Material properties:
Zvishandiso zvakasiyana-siyana zvine zvimiro zvakasiyana zvekudzikisa, uye zvakakosha kuti usarudze zvinhu zvinosangana nezvinodiwa zve14-layer inoshanduka PCB. Zvimwe zvakajairwa kunyorovesa zvinhu zvinosanganisira elastomers, viscoelastic polymers, furo, uye macomposites. Chinyorwa chega chega chine chayo chakasiyana zvimiro, senge kuomarara, viscoelasticity, uye simba rekutora simba. Kunzwisisa hunhu uhwu uye maitiro azvo pazvibration damping kugona kwakakosha pakuita sarudzo chaiyo.

3. Mafungiro ezvakatipoteredza:
Nzvimbo yebasa inoita basa rakakosha pakusarudza yakakodzera damping material. Zvinhu zvakadai sekuchinja kwekushisa, humidity mazinga uye kuratidzwa kumakemikari zvinogona kukanganisa kushanda kwezvinhu zvinonyorovesa. Zvakakosha kuongorora mamiriro ezvakatipoteredza umo 14-layer flex PCB ichashanda uye sarudza chinhu chinogona kumira mumamiriro ezvinhu aya pasina kukanganisa kukwanisa kwayo.

4. Kuchinja uye kuenderana:
Sezvo isu tiri kubata ne14-layer flexible PCB, kusarudzwa kwezvinhu zvinonyorovesa kunofanirwawo kufunga nezve kuchinjika uye kuenderana kweiyo inoshanduka substrate. Izvo zvinhu hazvifanirwe kukanganisa kuchinjika kwePCB uye zvinofanirwa kunamatira zvakasimba kumusoro kwayo. Zvinokurudzirwa kuita bvunzo yekuenderana kuti ive nechokwadi chekuti yakasarudzwa yekunyorovesa zvinhu haikanganise kushanda kweiyo inoshanduka PCB.

Dzivirira kukanganisa kwema mechanical vibration pamabhodhi edunhu:

1. Nzira dzekuisa kwadzo:
Pamusoro pekushandisa zvinhu zvinonyorovesa, nzira dzekuisa dzakakodzera dzakakosha kudzivirira mhedzisiro yemagetsi vibration pabhodhi redunhu. Kuisa zvakachengeteka iyo PCB kune yakavharirwa kana anti-vibration inokwira papuratifomu inobatsira kuderedza kutapurirana kwekudengenyeka kubhodhi. Yakanyatsogadzirwa michina inotsigira uye zvigadziriso zvinovimbisa kuti PCB inoramba yakagadzikana kunyangwe iri pasi pekunze vibration kana kuvhunduka.

2. Kusarudzwa kwechikamu:
Kusarudza zvinhu zvakasimba, zvinovimbika zvinokwanisa kushingirira kuzununguka uye kuvhunduka ndeimwe pfungwa yakakosha. Zvikamu zvine akavakirwa-mukati kuvhunduka uye vibration kuramba, senge yakasimbiswa solder majoini kana elastomeric encapsulation, inogona kuwedzera zvakanyanya kusimba kwese kwebhodhi redunhu. Izvo zvakakosha kuti ushande nemutengesi wako wezvikamu kuti usarudze zvinhu zvakakasharara zvakakodzera kune zvinotarisirwa kuzunguza mitoro.

3. Kuedza kwakasimba:
Chekupedzisira, zvinodikanwa kuti uedze zvine simba iyo 14-layer inochinjika PCB pane chikamu uye masisitimu mazinga kuti ive nechokwadi chekugona kwayo kutsungirira vibration uye kuvhunduka. Kufumura mabhodhi edunhu kune anomiririra mechanical vibration mamiriro uye kutarisa mashandiro avo kwakakosha kuti uone kushanda kwezvakasarudzwa zvinonyorovesa uye zvivhitivhiti zvekudzikisa zvinhu.

Mukupedzisa:

Kusarudza zvakakodzera kunyorovesa uye kudengenyeka-kudzikisa zvinhu kwakakosha kudzivirira kukanganisa kwemakanika vibration pa14-layer inochinjika PCB. Kufunga zvinhu zvakaita senge frequency renji, zvivakwa zvezvinhu, mamiriro ezvakatipoteredza, kuchinjika uye kuenderana kunogona kubatsira kuita sarudzo ine ruzivo.Pamusoro pezvo, kushandisa nzira dzekuisa dzakaringana, kusarudza zvinhu zvine rugged, uye kuita bvunzo dzakaomarara matanho akakosha ekuona kusimba kwebhodhi uye kuvimbika kubva pamechani vibration uye kuvhunduka. Nekutora matanho aya, kushanda uye hupenyu hwesevhisi hwePCB hunogona kuvimbiswa, nekudaro kuvandudza kushanda kwese kwechigadzirwa chemagetsi.
