Kutsvaga iyo yakakodzera potting zvinhu zvePCB

Kuwana izvo potting zvinhu zvePCB

Iyo PCB kana yakadhindwa yedunhu bhodhi ine zvakakosha zvikamu zvemagetsi. Izvi zvikamu zvinoda kuchengetedzwa kubva pakukuvadzwa. Mainjiniya emagetsi anoshandisa nzira dzakasiyana kuchengetedza zvikamu. Aya ndiwo conformal coating uye PCB yekubika.

Izvi zvinosanganisira kushandisa organic polymers kuchengetedza edunhu mabhodhi uye emagetsi zvikamu zvakabatana nazvo. Ivo vanouya nemisiyano uye zvakafanana, uye izvo zvaunotora zvinowanzoenderana nekushandiswa kwemagetsi.

PCB yekubika

PCB potting inodzivirira iyo substrate nekuzadza iyo yakavharirwa nekomboni yehari mune yemvura fomu. An encapsulation resin inogonawo kushandiswa. Komboni inozadza imba, uye, mune dzimwe nguva, chikamu chose kana bhodhi redunhu rakavharwa.

Iyi ndiyo imwe yedzakanakisa nzira dzekupa zvikamu abrasion resistance. Zvichienderana nekomboni yehari inoshandiswa, pane dziviriro kubva pakukanganisa, kudedera, makemikari, uye kupisa. Kune mamwe ari akanakisa ekuchengetedza njodzi yezvakatipoteredza. Mazuva ano zvinhu zvakajairika zvinosanganisira silicone, polyurethanes, epoxy, uye unsaturated polyesters.

Unofanira kushandisa conformal coating kana potting for PCBs?

Kana iwe uchinge wajairana neconformal uye PCB potting, unogona kutanga kufunga kuti ndeipi iri nani sarudzo. Mhinduro kumubvunzo iwoyo inowanzoenderana nemashandisirwo airi kushandiswa. Conformal uye PCB potting inoitirwa kupa dziviriro kune substrate kubva kune dzakasiyana njodzi kuti ive nechokwadi chekuti kutendeseka kwavo hakuna kukanganisa.

Kana iwe uri kubata neapplication inoda yakakwira kuramba makemikari, kupisa, abrasion, kukanganisa, uye vibration, iwe unofanirwa kusarudza PCB yekubika. Iyi ndiyo yakawedzera kusimba uye yakasimba sarudzo ndiyo yakanakira maapplication ari kudiwa nemuviri.

PCB potting inopa dziviriro kubva kune akasiyana magetsi arcs. Ichi ndicho chikonzero chinowanzoshandiswa mumagetsi emagetsi ane high voltage. Iyi nzira inokurumidza uye inogona kuitwa nyore mumitsara yegungano sezvinodiwa.

Kana iwe uchida kuongorora, kugadzirisa, kana kugadzirisa zvakare mudziyo wakabikwa, wakabikwa unogona kuve unonyengera uye unogona kupedzisira wakuvadza substrate yese. Conformal coatings zviri nyore kubata. Iwo machira haana kushushikana kwemuviri, achivabvumira kuchengetedza maPCB, kunyanya uko zvikamu zvinonzwa.

Conformal coatings zvakare inowanzotora nzvimbo shoma mukati mekuvharirwa kwemudziyo, izvo zvinoreva kuti huremu hwechishandiso hahuna kunyanya kukwira. Iyi isarudzo yakanaka kune zvishandiso uko uremu uye saizi zvine chekuita. Izvi zvinosanganisira maindasitiri akadai semagetsi anobatwa nemaoko.

Muindasitiri yemusangano wemagetsi, maumbirwo ehari akakosha zvikuru uye anopa kudzivirirwa kwakanyanya, kunyangwe mumamiriro ezvinhu akaoma. Ivo vanonatsiridza simba rechikamu nemakanika uye vanopa yakanakisa electric insulation.

Potting makomisheni anogona kushandiswa mumaindasitiri akasiyana akadai sevatengi vemagetsi, aerospace, uye mota. Kutsvaga mugadziri anonzwisisa kukosha kwemakomisheni ekuputira kwakakosha. Pazvinhu zvakadzika, isu tine maturusi akakodzera uye kuziva-maitiro ekugadzira iyo inonyanya kushanda yepoto makomisheni anogona kushandiswa mune akasiyana maapplication. Nekutsvagisa nekusimudzira, tiri pachinzvimbo chekupa musika mhinduro dzakanyanya kunaka. Isu tinokwanisa kugadzirisa-kugadzirisa mhinduro dzekusangana kunyangwe zvakanyanya kudiwa pamusika nhasi.
