Ibhodi yesekethe eshicilelweyo: inkcazelo, isikhundla

Ibhodi wesekethe eshicilelweyo yinto isakhi equka Heating isiseko nangobhedu abaqhubi, apho ifakwe kwi-zeendawana ngokohlobo macandelo metallized. Inika inamehlo lweziqalelo beesekethe elektroniki.

Ibhodi yesekethi kwiqela lokulungileyo kuthelekiswa ufakelo bulk (kwakuxhomekeke) esebenzisa iintambo kunye iingcingo:

• ingxinano High ezifuna inamacandelo koonomathotholo kunye nemixube zabo, kwaphumela ekuncipheni ngokubonakalayo ubukhulu kunye nobunzima baso;
• abafumana abaqhubi kunye uvikele imiphezulu, kunye nezinto ezinemitha kumjikelo zeteknoloji eyodwa;
• uzinzo, repeatability iimpawu ezifana capacitance, conductance, inductance;
• speed eliphezulu nengxolo okukwazi busebenze;
• ukumelana kwiimpembelelo koomatshini kunye zemozulu;
• ukufanisa isigama kolwimi kunye nomanyano kwezisombululo zeteknoloji kunye noyilo;
• kwiindibano ukuthembeka, iiyunithi kunye isixhobo liphela;
• ngcono processability ngenxa esizisebenzelayo oluntsonkothileyo imisebenzi ibandla, imisebenzi ulawulo kunye ulungiso;
• ngamandla yabasebenzi ephantsi, nentabalala yezinto eziphathekayo kunye neendleko.

Ibhodi yesekethe eshicilelweyo kananjalo ethile, kodwa ke kancinane: kuphela maintainability nokuntsonkotha eliphezulu ngokongeza utshintsho zoyilo.

Iziqalelo amakhadi ezinjalo ziquka isiseko Heating, yayisoma ebuntsimbi, nto leyo umzekelo ababhexeshi eziprintiweyo, pads contact; ukulungisa obandayo imingxuma.

Iimfuno ezisebenza nale mveliso GOST

• ibhodi yesekethe ezingamaphepha kufuneka abe umbala yohlobo olunye kwi zeendawana Heating ukuba monolithic kubume, musa ziqulathe vesicles zangaphakathi, zwe, inclusions amazwe, iintanda, iitshiphusi, iinyanda. Kodwa ukuba imikrwelo abangatshatanga, inclusions otyhidiweyo, ukususwa imizila neprotravlennogo isahlulo enye kunye nokuboniswa ngesakhiwo engeyoyangeli ukutshintsha izinto zombane parameters wemveliso, oku kunciphisa umgama avumelekile phakathi kwezakhi ipateni.
• Figure - ecacileyo, kunye ngohlangothi egudileyo, akukho namadyungudyungu, iintanda, bechuba, umkhondo isixhobo. amabala luncinane zalapha, kodwa iindawo hayi ngaphezulu kwe ezintlanu square decimeter nganye, phantsi kwelungiselelo elithi Ezinye ububanzi umkhondo iza elungelelene avumelekile zisezantsi; ivale ubude ku milimitha ezintandathu kunye nobunzulu microns 25.

Ukuphucula ukusebenza ngokudleka nokuphucula solderability ibhodi umphezulu kugalelwe yi kuqamba electrolytic ekufuneka zibe rhoqo, ngaphandle ukuxobuka, ikhefu kunye podgarov. Ukulungisa kunye nemingxuma ukuyinyusa kufuneka zilahlwe ngokungqinelana kumzobo. Ukuvunyelwa ukuba imali yeklasi accuracy kutenxa ichaziwe. Ukuze kuphuculwe ukuthembeka ngelotha kuzo zonke iindawo angaphakathi imingxuma ukuyinyusa spray umaleko lobhedu, ubukhulu bawo kufuneka microns ngaphantsi kwama-25. Le nkqubo ibizwa - metallization ezivuzayo.

Yintoni iiklasi PCB? Phantsi kolu luvo kuthetha kwiiklasi ngqo iibhodi beesekethe yokuvelisa, zinikwa yi GOST 23751-86. Kuxhomekeka indlela lexinene ibhodi yesekethe olushicilelweyo emihlanu iiklasi okuchaneka, ukhetho yayo emiselwe yi izixhobo zobugcisa kwinqanaba yeshishini elo. Iiklasi yokuqala neyesibini musa ukuba izixhobo nocoselelo kwaye zithathwa cheap ukuvelisa. Iiklasi yesine neyesihlanu ifuna izixhobo ezikhethekileyo, izixhobo ezizodwa, ucoceko egqibeleleyo kwizibonelelo zemveliso, air conditioning, ulawulo lobushushu. amashishini Domestic mass ukuvelisa iibhodi beesekethe eshicilelweyo kwiklasi yesithathu okuchaneka.
