Sherufu yehupenyu hwePCB?Nguva yekubika uye tembiricha?
Iyo nguva yekuchengetedza yePCB, uye tembiricha uye nguva yekushandisa oveni yeindasitiri kubheka PCB zvese zvinodzorwa neindasitiri. Chii chinonzi sherufu yePCB?Uye sei kuziva nguva yekubika uye tembiricha? 1. Iyo yakatarwa yePCB control 1. PCB kuburitsa uye kuchengetedza (1) The PCB bhodhi inogona kushandiswa zvakananga online mukati memwedzi ye2 yezuva rekugadzira rakavharwa uye risina kuvhurwa PCB board (2) Zuva rekugadzira bhodhi rePCB riri mukati memwedzi miviri, uye zuva rekuburitsa rinofanirwa kumakwa mushure mekuburitsa. (3) PCB board yekugadzira zuva iri mukati memwedzi miviri, mushure mekuburitsa, inofanira kunge iri online uye kushandiswa mukati memazuva mashanu. 2. PCB kubika (1) Kana PCB yakavharwa uye isina kurongedzerwa kweanopfuura mazuva mashanu mukati memwedzi miviri kubva pazuva rekugadzira, ndapota bika pa120 ± 5 ℃ kweawa imwe. (2) Kana PCB inopfuura mwedzi miviri kubva pazuva rekugadzira, ndapota ibike pa120±5℃ kweawa imwe usati waenda online. (3) Kana PCB iri 2-6 mwedzi yapfuura zuva rekugadzira, ndapota ibike pa120±5℃ kwemaawa maviri usati waenda online. (4) Kana PCB iri 6 mwedzi kusvika 1 gore rakakura kupfuura zuva rekugadzira, ndapota bika pa120±5 ° C kwemaawa mana usati waenda online. (5) PCB yakabikwa inofanira kushandiswa mukati memazuva mashanu (inoiswa muIR REFLOW), uye PCB inofanira kubikwa kweimwe awa isati yashandiswa paIndaneti. (6) Kana PCB yadarika gore kubva pazuva rekugadzira, ndapota bikai pa120±5℃ kwemaawa mana usati waenda online, wozoitumira kufekitori yePCB yekumwaya zvakare marata usati waenda online. 3. PCB kubika nzira (1) Mahombe maPCB (16 PORTs uye pamusoro, kusanganisira 16 PORTs) anoiswa akatwasuka, ane huwandu hwe30 zvidimbu mustack.Vhura ovheni mukati memaminitsi gumi mushure mekunge kubheka kwapera, tora PCB, woiisa pasi kuti itonhorese (inoda kudzvanya anti-plate bay fixture) (2) Madiki uye epakati-saizi maPCB (kusanganisira 8PORTs pazasi 8PORT) anoiswa akatwasuka.Nhamba yepamusoro ye stack ndeye 40 zvidimbu.Nhamba yemhando yakatwasuka haina muganho.Vhura ovheni uye tora PCB mukati memaminitsi gumi mushure mekunge kubika kwapera.Banwan fixture) 2. Kuchengetedza uye kubika kwePCB munzvimbo dzakasiyana Iyo chaiyo yekuchengetedza nguva uye yekubikira tembiricha yePCB haina hukama chete nehuwandu hwekugadzira uye maitiro ekugadzira ePCB mugadziri, asi zvakare ane hukama hukuru nedunhu. Iyo PCB yakagadzirwa neOSP maitiro uye yakachena kunyudza goridhe maitiro kazhinji ine pasherufu yemwedzi mitanhatu mushure mekurongedza, uye kazhinji hazvikurudzirwe kubikira maitiro eOSP. Iyo yekuchengetedza uye yekubheka nguva yePCB ine zvakawanda zvekuita nedunhu.Kumaodzanyemba, hunyoro hunowanzo kurema, kunyanya muGuangdong neGuangxi.Muna March naApril wegore rimwe nerimwe, kuchava “kudzokera kumaodzanyemba” okunze, uye kunonaya zuva riri rose.Zvakaramba zvakadaro, panguva iyi kwakanga kune mwando.PCB yakafumurwa kumhepo inofanirwa kushandiswa mukati memaawa makumi maviri nemana, zvikasadaro zviri nyore kuita oxidize.Mushure mekuvhura kwakajairika, zviri nani kuishandisa mumaawa masere.Kune mamwe maPCB anoda kubikwa, nguva yekubika ichave yakareba.Mumatunhu ekuchamhembe, mamiriro ekunze anowanzo kuoma, iyo PCB yekuchengetedza nguva ichave yakareba, uye nguva yekubika inogona kupfupika.Tembiricha yekubikira inowanzo 120 ± 5 ℃, uye nguva yekubika inotarwa zvichienderana nemamiriro chaiwo. Yenguva yekuchengetera PCB, nguva yekubikira uye tembiricha, matambudziko chaiwo anofanirwa kuongororwa zvakadzama, uye kusarudzwa chaiko kunoda kuitwa pahwaro hwePCB manejimendi uye kudzora maratidziro, zvichienderana nekugadzira kugona, maitiro, dunhu uye mwaka wevagadziri vakasiyana. .
