Chii chinonzi Potting Material yeElectronics Components

Potting compound kwakakosha pakudzivirira mabhiti emagetsi akapfava uye akakosha kubva munjodzi. Kunyangwe iyo yakaoma kwazvo yekuongorora mamiriro, inopa yakawanda-inodiwa dziviriro - kwete chete nekusimudzira mechaniki kusimba asiwo nekukudza magetsi ekudzivirira.

Kubva kumagetsi evatengi kuenda kune aerospace, mota, uye mamwe makambani uko zvemagetsi zvigadzirwa zvemagetsi zvakanyanya, potting makomisheni anowanikwa kwese!

Chii chinonzi Potting Material yeElectronics Components?

Wakambovhura mudziyo wemagetsi chete kuti uwane bhodhi rose kana kuti casing yakavharirwa zvachose mune imwe mhando yeakaoma epoxy? Ehe, ndozvinoita musanganiswa wemagetsi - resin inonamira inoshandiswa kuvharidzira zvemagetsi uye kuvadzivirira kubva kune chero nharaunda yavangazopedzisira vari mairi.

Zvichienderana nechinangwa kana kudiwa kwedziviriro, kune akasiyana makomisheni anowanikwa ane zvimiro zvakasiyana zvishoma. Saka, kana yave nguva yekushongedza midziyo yako yepamusoro-soro kurwisa Amai Nature - maumbirwo emagetsi ekuputira akakufukidzira!

 

Kusiyana kwePotting Zvishandiso zveElectroniki Zvikamu

Kudzivirirwa kwakakosha, izvo zvinoita kuti maumbirwe akakosha - uye zvigadzirwa zvawo zvinoenderana nezviri kuchengetedzwa. Tora urethane (kana kuti polyurethane) semuenzaniso: vana vemagetsi-potting vanogona kutora kupisa, kukwira kudenga kusvika 120°C. Ndicho chikonzero ivo vakakwana kune super-yakasimba maseketi kana ekunze magetsi anotarisana nemamiriro ekunze akanyanya.

Kudivi refiripi, silicone yemagetsi potting makomisheni anogona kuuya anobatsira kudzivirira mwenje kubva kune ultraviolet mwaranzi uye kuchengetedza ruvara rwavo rwakajeka. Asi iwe unofanirwa kuve nechokwadi chekuti unowana mhando chaiyo - mamwe anogadzira kupisa panguva yekurapa uye anogona kutokonzera kukuvadza kune mamwe maIC, tisingataure kuti kana yangove ipapo, hapana kudzokera kumashure.

 

Chii chinonzi Kushandiswa kwePotting Materials?

Sezvandambotaura, musanganiswa wehari unogadzira nzvimbo yakachengeteka yemagetsi, ichivagonesa kuchinjanisa mweya vachiri kuchengetedzwa kubva kunjodzi dzinogona kukanganisa nharaunda sekupisa uye ngura. Uyezve, inogona kuwedzera imwe nguva pasherufu yechinhu!

Transformers ndiyo nzira yekuenda kana iwe uchitsvaga yemagetsi potting komboni sezvo ivo vane zvimwe zvakanaka zviri nyore maficha; mazinga avo ekupisa uye kuwedzera kwekudzivirira kubva kumagineti nemagetsi emagetsi anoita kuti zvive zvakanyanya kuvimbika kushandiswa. Uyezve, neiyo foil yekuputira iwe yaunowana, haufanirwe kunetseka nezve chimwe chinhu chiri kutadza!

 

Chii chinonzi Chemistry yePotting Materials?

Pasina kupokana, potting yemagetsi inouya mumhando nhatu huru: epoxy resins, silicones uye urethane-based (polyurethanes kana PU). Mhando yega yega yekuputira ine yayo yakasarudzika maapplication uye mabhenefiti. Asi tisati tapinda mune zvakatemwa zvekomboni imwe neimwe, pane chinhu chimwe chekurangarira - zvinhu izvi zvinoumbwa nemakemikari ane simba anogona kutsungirira nguva pamwe nemamiriro akanyanya.

Nekudaro, hazvifanirwe kushamisa kuti kuzvibata kunoda hunyanzvi hwekushandisa uye zvakadzorwa marongero - kunyanya kana zvasvika kune resin kurapa maitiro ayo anoburitsa zvigadzirwa sehutsi hwegasi!

 

Pfupiso yePCB Potting process

Izvo zvakakosha kuti kuumbwa kwakabudirira kwePCB kugadzika bhodhi mune imwe casing, inozivikanwa se'potting box'. Zvose zvaunofanirwa kuita ndezvokuzadza nemagetsi emagetsi kusvikira asangana nemazinga anodiwa.

Chikamu chekurapa chinogona kutora zvishoma semaminetsi (zvichienderana nemidziyo yepasi) kudzamara komisheni yaoma, kuchengetedza nyaya yako nePCB nemukati. Imwe inodhura-inoshanda imwe nzira inowanzo shandiswa isiri-epoxy reactive mapurasitiki makesi: nekukurumidza uye nyore kuisa.

 

Ko Potting Yakasiyana Sei neEcapsulation?

Kugadzika hakufanirwe kuve nzira iyo iyo PCB yakafukidzwa zvizere - kune mamwe mabasa, kuumba kunogona kuve nyanzvi yekudira pamusoro pezvimwe zvikamu; iyo inonzi PCB encapsulation.

Uchicherekedza kuti kana zvasvika pa "kubira" - funga nezvayo seine nyaya dzese dzakatenderedza chinhu chine komboni kuchiisa chisimbiso pasina kuparadzaniswa. Encapsulation inotora iyi pfungwa nhanho imwe mberi, ichiita mukubviswa kweresin / bhodhi muviri kubva mumudziyo wayo mushure.

 

Ndeipi Iyo Yakanakisa Potting Material yeElectronics Zvikamu?

Zvichienderana nekuumbwa kwemuumbi wehari, kushandiswa kwayo uye kushandiswa kuchasiyana - sezvatakambokurukura. Epoxy resins yakanakira SMT application nekuda kweakanakisa makemikari kuramba uye kupisa kushivirira.

Kutaura nezve PU potting makomisheni, iwo ndiwo chaiwo dhiri kana zvasvika kune yakaderera temp kutsungirira uye kupisa bhasikoro. Kana ari masikirwo esilicone, haana kunyanya kushambidzika - makuru ekutsungirira zvivakwa uye achiri akavimbika pasi pekupisa-kutonhora kushanduka.

 

Ndeipi Nguva Yekuputira Zvishandiso?

Tembiricha inogona kuve chiyero chakaomarara kune chero kusimba kwemuumbi wehari - akapfava kana silicone resins anowanzo mira zvirinani pamusoro penguva refu yekudziya kutenderera, asi iyo yakanyanya kusimba epoxy-based resins inogona kugara kwehupenyu hwese!

Tiri kutaura kusvika ku1500 kutenderera kwekushisa kukuru kwekuchinja pasina kurasikirwa nesimba ravo - izvo zvinoturikirwa zviri nyore mumakore ekushandiswa kwakavimbika mumunda.

 

Kurapa kwePotting Kunotora Nguva Yakadii?

Zvichienderana nerudzi rweresin inoshandiswa, nguva yekurapa inogona kubva pamasekonzi gumi chete kusvika makumi matatu kune UV-based resin kusvika kumaminitsi gumi nemashanu epoxy potting compounds. Ramba uchifunga kuti mamwe macommunication anogona kupa hutsi hune ngozi uye kuburitsa kupisa panguva iyi - ndosaka zvakakosha kutora matanho ekuchengetedza anodiwa uye magadzirirwo ekufunga usati washandiswa.

Usakanganwa kuti kugadzirira yako yakasarudzwa potting compound ndiyo kiyi; iwe unongoda musanganiswa wakakodzera wezvinhu zveresin zvine kumhanya kwakakodzera kwekuparadzira uye tembiricha yakakwana yekushandisa.

 

Zvinoita Here Kubvisa Potting Materials?

Depotting, kana kubvisa inodzivirira potting compound, inogona kusiyana zvakanyanya zvichienderana nehwaro zvinhu. Semuenzaniso, nemafuta akaomarara, kuisa acetone uye kupisa kunogona kunyungudutsa zvikamu zvayo - kana zvisati zvapora.

Nekudaro, kana iyi isiri sarudzo nekuda kwekuti resin yatoomeswa, simba remuviri rinogona kushandiswa (asi isu hatikurudzire kuti uedze!). Chechipiri kune makemikari ane njodzi anogona kushanda pakuisa. Kunze kwekunge zvaitwa munzvimbo yakakodzera zvakadaro izvi zvinhu zvine njodzi zvinoisa zvese zvemagetsi zvikamu uye iwe panjodzi saka gara kure!

Final Thoughts

Munyika yanhasi, zvemagetsi zviri kwese kwese, zvichiita kuvandudza kwakakura kuhupenyu hwevanhu nenzira yemidziyo midiki yemunhu uye akakura otomatiki maindasitiri ekuisa. Kuchengetedza zvinhu izvi zvakatetepa zvakachengeteka kubva munzvimbo yazvo inogara ichichinja - kubva kumakemikari anoparadza uye guruva zvidimbu kusvika kune yakanyanyisa tembiricha uye mavhitamini - maumbirwo ehari akakosha.
