Ukufumana ilungelo izinto zokubumba zePCB

I-PCB okanye ibhodi yesekethe eprintiweyo inamacandelo abalulekileyo e-electronics. La malungu kufuneka akhuselwe kumonakalo. Iinjineli zombane zisebenzisa iindlela ezahlukeneyo zokukhusela amalungu. Ezi zityatyekwe ngokusemthethweni kunye PCB potting.

Oku kubandakanya ukusebenzisa iipolymers eziphilayo ukukhusela iibhodi zeesekethe kunye nezinto ze-elektroniki ezinxulumene nazo. Ziza nokwahluka kunye nokufana, kwaye into oyikhethayo ihlala ixhomekeke ekusetyenzisweni kombane.

PCB potting

I-PCB potting ikhusela i-substrate ngokugcwalisa i-enclosure kunye ne-potting compound kwi-liquid form. I-resin ye-encapsulation nayo ingasetyenziswa. Ikhompawundi igcwalisa indlu, kwaye, kwezinye iimeko, yonke icandelo okanye ibhodi yesekethe igqunyiwe.

Le yenye yeendlela ezilungileyo zokunika amacandelo ukuxhathisa kwe-abrasion. Ngokuxhomekeke kwikhompawundi yokubumba esetyenzisiweyo, kukho ukhuseleko kwimpembelelo, ukungcangcazela, iikhemikhali, kunye nobushushu. Kukho ezinye ezona zilungileyo kukhuseleko lwengozi yokusingqongileyo. Ezona zinto ziqhelekileyo namhlanje ziquka i-silicone, i-polyurethanes, i-epoxy, kunye ne-polyester ezingaxutywanga.

Ngaba kufuneka usebenzise i-coating esemthethweni okanye imbiza yeePCB?

Xa uqhelana ne-conformal kunye ne-PCB potting, unokuqalisa ukuzibuza ukuba yeyiphi eyona ndlela ingcono. Impendulo yalo mbuzo idla ngokuxhomekeke kwizicelo esetyenziselwa yona. Ukubunjwa ngokusesikweni kunye ne-PCB kujoliswe ekunikezeni ukhuseleko kwi-substrate kwiingozi ezahlukeneyo ukuqinisekisa ukuba ingqibelelo yabo ayithotywanga.

Ukuba ujongene nesicelo esidinga ukuxhathisa okuphezulu kwimichiza, ubushushu, ukukrazuka, impembelelo, kunye nokungcangcazela, kufuneka ukhethe PCB potting. Olu lolona khetho lomelele ngakumbi kwaye lolona lufanelekileyo kwizicelo ezifunwa ngokwasemzimbeni.

PCB potting inika ukhuselo ngokuchasene arcs zombane ezahlukeneyo. Kungenxa yoko le nto isetyenziswa ngokuqhelekileyo kwizixhobo zombane ezinombane ophezulu. Le ndlela ikhawuleza kwaye inokwenziwa lula kwimigca yokuhlanganisa njengoko ifunwa.

Xa ufuna ukuhlola, ukulungisa, okanye ukuphinda usebenze isixhobo esenziwe ngembiza, esithe safakwa ebhodweni sinokukhohlisa kwaye sinokuphela sonakalise yonke i-substrate. Iingubo ezihambelanayo zilula ukuphatha. I-coatings ayinalo uxinzelelo lomzimba, lubavumela ukuba bakhusele ii-PCBs, ngakumbi apho amacandelo anovelwano.

Iingubo ezihambelanayo zivame ukuhlala kwindawo encinci ngaphakathi kwendawo ebiyelweyo yesixhobo, okuthetha ukuba ubunzima besixhobo abukho phezulu kakhulu. Olu lukhetho oluhle kwizixhobo apho ubunzima kunye nobukhulu buchaphazelekayo. Oku kubandakanya amashishini afana ne-elektroniki ephathwayo.

Okukwintsusa

Kwishishini lendibano ye-elektroniki, iikhompawundi zokubumba zibaluleke kakhulu kwaye zibonelela ngokhuseleko olusebenzayo, nakwiimeko ezinzima. Baphucula amandla ecandelo ngoomatshini kwaye banikezela ngeyona ndlela yokugquma umbane.

Iikhompawundi zePotting zinokusetyenziswa kumashishini ahlukeneyo afana nabathengi be-elektroniki, i-aerospace, kunye neemoto. Ukufumana umenzi oqondayo ukuba kubaluleke kangakanani iikhompawundi zokubumba. Kwizinto ezinzulu, sinezixhobo ezifanelekileyo kunye nokukwazi ukwenza iikhompawundi zobumba ezisebenzayo ezinokuthi zisetyenziswe kwizicelo ezahlukeneyo. Ngophando kunye nophuhliso, sikwimo yokubonelela imarike ezona zisombululo zibalaseleyo. Sinokwenza izisombululo ngokwesiko ukuhlangabezana nezona mfuno zikhethekileyo kwimarike namhlanje.

Sinikezela ngesikhokelo kwizinto ezilungele useto oluthile ngelixa sinikezela ngeemveliso ezahlukeneyo kubathengi bethu.
