Chiziviso (Soldering uye Mounting)
1. Kukwira
Paunenge uchiisa pini terminal rudzi rwechigadzirwa kune rakadhindwa redunhu bhodhi, ndapota isa pini terminal padivi peburi rebhodhi.Kana chigadzirwa chikatsikirirwa kuitira kuti terminal isave mugomba, pini terminal inosaidzirwa mukati mechigadzirwa uye manzwi anogona kusagadzikana.
2. Kaviri-sided through-gole Bhodhi Ndokumbira usashandise kaviri-sided through-buri board.Kana solder yakanyungudutswa ikabata pasi pepini terminal, chikamu chepurasitiki chaizonyunguduka uye ruzha rwaigona kusagadzikana.
3. Soldering Conditions
(1) Flow soldering mamiriro epini terminal mhando
· Tembiricha: mukati me260°C±5°C
Nguva: mukati me10±1 sec.
· Soldering chikamu ndiyo inotungamira terminals isingasanganisire 1.5mm kubva kune chigadzirwa muviri.
(2) Ndapota usachengeta zvigadzirwa zvakananga pasi pasina chero chinhu chiri pasi pazvo kudzivirira nzvimbo dzine unyoro uye / kana nzvimbo dzine guruva.
(3) Ndokumbira usachengete chigadzirwa munzvimbo dzakaita semunzvimbo ine unyoro inopisa kana chero nzvimbo inovhenekerwa nechiedza chezuva kana kuzunguza kwakanyanya.
(4) Ndapota shandisai zvigadzirwa pakarepo mushure mekuvhurwa kwepakiti, nokuti maitiro anogona kuderedzwa muhutano, uye / kana kuderedzwa mukutengesa nekuda kwekuchengetedza pasi pemamiriro asina kunaka.
(5) Ndokumbira utarise nemumiriri wedu wekutengesa kana mainjiniya pese apo zvigadzirwa zvichashandiswa mumamiriro asina kunyorwa pamusoro.
4. Nzvimbo Yekushanda
Ichi chigadzirwa chakagadzirirwa kushandiswa munzvimbo yakajairwa (yakajairika tembiricha yekamuri, humidity uye kumanikidzwa kwemhepo).
Usashandise zvigadzirwa mumhepo yemakemikari senge chlorine gasi, asidhi kana sulfide gasi.
Hunhu hunogona kudzikisira nekuita kwekemikari nezvinhu zvinoshandiswa muzvigadzirwa.
(2) Soldering mamiriro ne soldering iron yepini terminal mhando
· Tembiricha: mukati me350±5°C
Nguva: mukati me3.0±0.5 sec.
· Soldering chikamu ndiyo inotungamira terminals isingasanganisire 1.5mm kubva kune chigadzirwa muviri
(3) Reflow soldering mamiriro ekukwira pamusoro pemhando
· Kupisa chimiro: Fig. 1
· Nhamba yenguva: Mukati me2 yakanyanya
4. Kugeza
Ndapota dzivisa kushambidza, sezvo chigadzirwa ichi hachisi chimiro chakavharwa.
5. Mushure meKuisa Chigadzirwa
(1) Kana chigadzirwa chacho chichiyangarara kubva pabhodhi redunhu rakadhindwa, ndapota usachisundire.Paunenge uchidzvanya, pini terminal inosundirwa mukati mechigadzirwa uye manzwi anogona kuve asina kugadzikana.
(2) Ndapota usashandise simba (kuvhunduka) kune chigadzirwa.Kana simba rikashandiswa, nyaya yacho inogona kubuda.
(3) Kana nyaya yacho ichibva, ndapota usabatanidza zvakare.Kunyange ikaita seyakadzokera kune yepakutanga, manzwi anogona kusagadzikana.
(4) Ndapota usafuridzira mweya pane chigadzirwa zvakananga.
Mhepo inoputika inoshandisa simba kune piezoelectric diaphragm kuburikidza negomba rekuburitsa inzwi;kutsemuka kwaigona kuitika uye ipapo ruzha rwaigona kusagadzikana.Mukuwedzera, pane mukana wekuti nyaya yacho inogona kubuda.
Notice (Kubata)
1. Piezoelectric ceramic inoshandiswa muchigadzirwa ichi.Ndapota shandisa hanya mukubata, nekuti ceramic inotyoka kana simba rakawandisa rikaiswa.
2. Ndapota usashandise simba kune piezoelectric diaphragm kubva pagomba rekubudisa inzwi.Kana kushandisa simba, kutsemuka kunoitika uye manzwi anogona kusagadzikana.
3. Ndapota usadonhedze chigadzirwa kana kushandisa kuvhunduka kana kuchinja kwekushisa kwairi.Kana zvirizvo, iyo LSI inogona kuparadzwa nechaji (surge voltage) inogadzirwa.inoratidza muenzaniso wekutyaira wedunhu uchishandisa zener diode.
Notice (Kutyaira)
1. Ag migration inogona kuitika kana DC voltage ikaiswa kuchigadzirwa pasi penzvimbo ine mwando wepamusoro.Ndokumbira usashandise pasi pehunyoro hwepamusoro uye gadzira dunhu kuti usashandise DC voltage.
2. Paunenge uchityaira chigadzirwa neIC, ndapota isa kupikisa kwe1 kusvika ku2kΩ mumutsara.Chinangwa ndechekudzivirira IC uye kuwana ruzha rwakagadzikana.(Ndapota ona mufananidzo 2a).
Kuisa diode mukuenderana kune chigadzirwa kune zvakafanana.(Ndapota ona mufananidzo 3b)
3. Flux kana Coating Agent, nezvimwewo, Various Solvents
Zvinogoneka kuti mvura inonyungudutsa ipinde mukati mechigadzirwa, sezvo chigadzirwa ichi hachisi chimiro chakavharwa.Kana mvura ikapinda mukati uye yakanamatira piezoelectric diaphragm, kudedera kwayo kwaigona kudziviswa.Kana ukasungirira pajonji yemagetsi, kubatanidza kwemagetsi kunogona kutadza.
Kuti udzivise kusagadzikana kwezwi, ndapota usabvumira mvura kupinda mukati mechigadzirwa.
