Makhalidwe Amagetsi

PS: Vp-p ＝1/2duty , mafunde a sikweya

Miyeso ndi Zinthu Zofunika

Pogwiritsa ntchito ukadaulo waukulu wa kapangidwe ka mawu ndi makina komanso zoumba zadothi zogwira ntchito bwino, zoyimbira za SMD piezoelectric zimagwirizana ndi kapangidwe kowonda komanso kolemera kwa zida zamagetsi.

Mawonekedwe

1. Kakang'ono, kowonda komanso kopepuka
2. Kuthamanga kwa phokoso kwambiri komanso phokoso lomveka bwino
3. Kubwerera m'mbuyo
4. Kupereka tepi ndi Reel

Mapulogalamu

1. Zipangizo zosiyanasiyana zaofesi monga makina osindikizira a PPC ndi makiyibodi
2. Zipangizo zapakhomo monga uvuni wa microwave, zophikira mpunga ndi zina zotero.
3. Kutsimikizira mawu a zida zosiyanasiyana zomvera

Chidziwitso (Kusungunula ndi Kuyika)

1. Kuyika
Mukayika chinthu cha mtundu wa pini terminal ku bolodi losindikizidwa, chonde ikani pini terminal m'bowo la bolodi. Ngati chinthucho chakanidwa kotero kuti terminalyo isakhale m'bowo, pini terminal idzakankhidwira mkati mwa chinthucho ndipo mawuwo akhoza kukhala osakhazikika.

2. Bolodi lodutsa mbali zonse ziwiri
Chonde pewani kugwiritsa ntchito bolodi lokhala ndi mabowo awiri. Ngati chosungunula chosungunukacho chikakhudza pansi pa cholumikizira cha pini, gawo lina la chikwama cha pulasitiki lingasungunuke ndipo mawuwo angasinthe.

3. Mikhalidwe Yogulitsira
(1) Mikhalidwe yolumikizira madzi pamtundu wa pini
· Kutentha: mkati mwa 260°C±5°C
· Nthawi: mkati mwa 10±1 sekondi.
· Gawo losungunula ndi malo otsogolera osaphatikiza 1.5mm kuchokera ku thupi la chinthucho.
(2) Chonde musasunge zinthuzo pansi popanda chilichonse pansi pake kuti mupewe malo onyowa ndi/kapena malo afumbi.
(3) Chonde musasunge mankhwalawa m'malo monga pamalo onyowa ndi otentha kapena pamalo aliwonse omwe ali ndi dzuwa kapena kugwedezeka kwambiri.
(4) Chonde gwiritsani ntchito zinthuzo nthawi yomweyo phukusi litatsegulidwa, chifukwa makhalidwe ake akhoza kuchepa mu ubwino, kapena kuwonongeka chifukwa chosungira zinthu m'malo oipa.
(5) Chonde onetsetsani kuti mwafunsana ndi woimira malonda athu kapena mainjiniya nthawi iliyonse yomwe zinthuzo zikuyenera kugwiritsidwa ntchito m'mikhalidwe yomwe sinatchulidwe pamwambapa.

4. Malo Ogwirira Ntchito
Chogulitsachi chapangidwa kuti chigwiritsidwe ntchito pamalo wamba (kutentha kwabwinobwino kwa chipinda, chinyezi ndi kuthamanga kwa mpweya). Musagwiritse ntchito zinthuzi pamalo okhala ndi mankhwala monga mpweya wa chlorine, asidi kapena sulfide. Makhalidwe ake akhoza kuwonongeka ndi momwe mankhwala amachitira ndi zinthu zomwe zimagwiritsidwa ntchito muzinthu.
(2) Kusokedwa kwa chitsulo pogwiritsa ntchito chitsulo chosokedwa cha mtundu wa pini
· Kutentha: mkati mwa 350±5°C
· Nthawi: mkati mwa masekondi 3.0±0.5.
· Gawo losungunula ndi malo otsogolera osaphatikizapo 1.5mm kuchokera ku thupi la chinthucho
(3) Momwe mungasinthirenso soldering pa mtundu woyika pamwamba
· Mbiri ya kutentha: Chithunzi 1
· Chiwerengero cha nthawi: Mkati mwa nthawi ziwiri zokha

5. Kusamba
Chonde pewani kusamba, chifukwa mankhwalawa si otsekedwa.

6. Mukayika Chogulitsacho
(1) Ngati chinthucho chikuyandama kuchokera pa bolodi losindikizidwa, chonde musakankhire. Mukakanikiza, cholumikizira cha pini chimakankhira mkati mwa chinthucho ndipo mawuwo akhoza kukhala osakhazikika.
(2) Chonde musagwiritse ntchito mphamvu (kugwedeza) pa chinthucho. Ngati chikugwiritsidwa ntchito mphamvu, chikwamacho chingatuluke.
(3) Ngati chikwamacho chatsekedwa, chonde musachisonkhanitsenso. Ngakhale chikuwoneka ngati chabwerera ku choyambirira, mawu ake akhoza kukhala osakhazikika.
(4) Chonde musapumire mpweya mwachindunji pa chinthucho. Mpweya wopumira umayika mphamvu pa diaphragm ya piezoelectric kudzera mu dzenje lotulutsa mawu; ming'alu ingachitike kenako mawuwo akhoza kusakhazikika. Kuphatikiza apo, pali kuthekera kuti chikwamacho chingatuluke.

Chidziwitso (Kusamalira)

1. Piezoelectric ceramic imagwiritsidwa ntchito mu izi. Chonde samalani pogwira ntchito, chifukwa ceramic imasweka mukagwiritsa ntchito mphamvu zambiri.
2. Chonde musagwiritse ntchito mphamvu pa diaphragm ya piezoelectric kuchokera pa dzenje lotulutsa mawu. Mukagwiritsa ntchito mphamvu, ming'alu imachitika ndipo mawuwo akhoza kukhala osakhazikika.
3. Chonde musagwetse chinthucho kapena kuchiyika pa shock kapena kusintha kwa kutentha. Ngati ndi choncho, LSI ikhoza kuwonongeka ndi mphamvu (surge voltage) yopangidwa. Ikuwonetsa chitsanzo cha driving circuit pogwiritsa ntchito zener diode.

Chidziwitso (Kuyendetsa)

1. Kusamuka kwa magetsi kungachitike ngati magetsi a DC agwiritsidwa ntchito pa chinthucho pamalo omwe chinyezi chili chachikulu. Chonde pewani kugwiritsa ntchito pa malo omwe chinyezi chili chachikulu ndipo pangani dera kuti lisagwiritse ntchito magetsi a DC.
2. Mukayendetsa chinthucho ndi IC, chonde ikani kukana kwa 1 mpaka 2kΩ motsatizana. Cholinga chake ndikuteteza IC ndikupeza phokoso lokhazikika. (Chonde onani Chithunzi 2a). Kuyika diode motsatizana ndi chinthucho kuli ndi zotsatira zomwezo. (Chonde onani Chithunzi 3b)
3. Flux kapena Coating Agent, etc., Zosungunulira zosiyanasiyana N'zotheka kuti chosungunulira chamadzimadzi chilowe mkati mwa chinthucho, chifukwa chinthuchi si chotsekedwa. Ngati madzi alowa mkati ndi kulumikizidwa ku diaphragm ya piezoelectric, kugwedezeka kwake kungalephereke. Ngati atalumikizidwa ku malo olumikizira magetsi, kulumikizana kwa magetsi kungalephereke. Kuti mupewe kusakhazikika kwa mawu, chonde musalole madzi kulowa mkati mwa chinthucho.
