chojambulira chamutu wopanda mutu SMT Pj-381-4p chojambulira chamutu cham'makutu
Ubwino wazinthu:
Kutumiza mwachangu, zitsanzo zaulere, zopangidwa ndi lipoti la mayeso la SGS RoHS, moyo wozungulira nthawi zopitilira 5000,kutentha kwakukulu kwa chigamba,kutsimikizika pambuyo pogulitsa ntchito, chithandizo chaukadaulo komanso mawonekedwe abwino autumiki
Minda yofunsira:
Zogulitsa m'makutu, zida ndi zida, zamagetsi ogula, zida zapakhomo, zotetezedwa, zida za hi-fi, zida zamamvekedwe
Mphamvu zamafakitale:
Ndi zaka 13 zamakampani, kampaniyo yadutsa chiphaso cha ISO9001, ziphaso zingapo zapatent, makasitomala ogwirizana opitilira 5300, makasitomala ambiri amakampani omwe adatchulidwa, antchito 106, nkhonya 12 za Hardware, makina opangira jakisoni 18, makina 26 okhazikika okhazikika. , makina 32 odziyesera okha, makina 21 odziyesera okha, makina 12 oyesera moyo ndi zida zina 25 zoyesera
Zogulitsa zathu zimakwaniritsa zomwe zili pansipa ndipo zimatha kuyesa zotsatirazi:
1) kutentha osiyanasiyana:gwiritsani ntchito mkati mwa -30 ~ 70ºc
2) mulingo wanthawi zonse wammlengalenga popanga miyeso ndi mayeso ndi motere:
(1) pakati pa thupi ndi kondakitala: 5ºc mpaka 35 ℃
(2) pakati kondakitala kuti kukhudzana:45% mpaka 85%
(3) kupanikizika:86kpa mpaka 106kpa
3) kugwirizana ndi mphamvu yolekanitsa
muyeso udzapangidwa pambuyo kulumikiza ndi disconnecting ntchito muyezo pulagi n'zotsimikizira 3 nthawi, kugwirizana ndi kumasuka mphamvu 5-15n.
4) mphamvu yotsiriza
Katundu wosasunthika wa 0.1n/m(1kgf/cm) aziyikidwa kunsonga ya kothera kwa mphindi imodzi mbali iliyonse.
sipadzakhala kuwonongeka kwa terminal monga ming'alu, kumasuka kapena kusewera magetsi, ndipo mawonekedwe amakina adzakwaniritsidwa.
5) kukana kukhudzana
kuyeza pamadzi ang'onoang'ono(100m kapena kuchepera）1000hz, kukana kukhudzana ≤30mω
6) kukana kutchinjiriza
ikani mphamvu yamagetsi ya 500v dc kwa mphindi imodzi kugawo lotsatira lomwe muyeso upangidwe:
(1) pakati pa thupi ndi kondakitala
(2) pakati kondakitala kuti kukhudzana
(3) pakati kondakitala sayenera pamene pulagi anaikapo dc 500v 1 min kutchinjiriza kukana ≥100mω
7) mlingo:dc 30v 0.2a
8) mphamvu ya dielectric: ac 250v ims (50~60hz) kwa 1 min ulendo wapano: 0.5ma
(1) pakati pa thupi ndi kondakitala
(2) pakati pa kondakitala kuti asakhale contacl
(3) pakati pa ma conductor sayenera kukhala pulagi ikayikidwa dc 250v 1 min
9) mayeso a solderability
pamwamba pa materminal adzakhala choviikidwa 1mm mu solder kusamba 240±5℃ kwa 3±0.5 masekondi.
10) kukana soldering kutentha mayeso reflow soldering mikhalidwe:
Preheat: kutentha pa zojambula zamkuwa pamwamba ayenera kufika 180 ℃.120s pambuyo pcb
adalowa mu zida za soldering.kutentha kwambiri: kutentha pamwamba pa zojambulazo zamkuwa kuyenera kufika pa kutentha kwakukulu kwa 260 ± 5 ℃ ndi masekondi 20.
11) kukana kuyesa kutentha kwa soldering
Njira yothetsera chitsulo:
pang'ono kutentha 330 ± 5 ℃ ntchito
nthawi ya soldering iron3 ± 0.5 sec
komabe kupanikizika kwakukulu sikudzagwiritsidwa ntchito ku terminal
13) mayeso a chinyezi
jack adzasungidwa kutentha
wa 40 ± 2 ℃ ndi chinyezi cha 90% mpaka 96% kwa 96 hr, ndiye jack iyenera kusungidwa mumlengalenga wamba kwa 1 hr pazochita zina.
14) kuyesa kutentha
Thefonijack idzasungidwa kutentha kwa70±2℃ kwa maola 96,ndiyeno idzaperekedwa ku mbasurbm yowongolera yochira
15) mayeso ozizira
jack idzasungidwa kutentha kwa-25 ± 3 ℃ kwa maola 96 ndipo kenako idzayang'aniridwa ndi kuchira kwa ola limodzi pambuyo pake.
16) mayeso a moyo
pa rating condition(katundu wopanda inductive）
kulumikizidwa ndi kulumikizidwa kudzapangidwa kuzungulira kwa 5000 pa liwiro la 10 mpaka 20 kuzungulira / mphindi
17) mayeso oziziritsa ndi kutentha
Jackyo adzayendetsedwa mozungulira 5 pazotsatira zotsatirazi zomwe zikuwonetsedwa pachithunzichi, kenako adzabwerera ndikuloledwa kukhala m'chipinda chozungulira kwa mphindi 30..
Tsipadzakhala ming'alu kapena ming'alu.Kuyika&mphamvu yotulutsa: 3 mpaka 20n
kukana kukhudzana: max.30mω
kukana kutchinjiriza: min.100 mω
dielectric kupirira voteji: 500vac/mphindi (pakati ma terminals)
