Heano mamwe mazano enyanzvi ekuita sarudzo iyi:
1. Kukwanisa
Panyaya yekuenzanisa pakati peHASL inotungamira-isina uye HASL inotungamira, tingati iyo yekutanga inodhura zvakanyanya.Naizvozvo, kana iwe uri pabhajeti rakasimba kana uchida kuchengetedza mari, kuenda kune HASL inotungamira kupedzisa inzira iri nani yekuchengetedza mari.
2. RoHS kutevedza
Tichifunga nezvehutano uye kukuvadzwa kwemuviri nyaya dzine chekuita nekushandiswa kwemidziyo yemagetsi, kudzika kwekuratidzira uko kuyambuka-kutarisa bhodhi redunhu kunounza kumushandisi kwakakosha.
Kuteerera kweRoHS ikozvino ndiyo chiyero chezvizhinji zvePCB mapurojekiti uye vatengi vazhinji vari kuterera munzira iyi.Nechikonzero ichi, kusarudza HASL inotungamira-yemahara zvigadzirwa isarudzo iri nani kana iwe uchida kugadzira RoHS-inoenderana edunhu mabhodhi.
Izvi zvakadaro nekuda kwekuwanda kwerata uye nemhangura shoma.Sezvo pasina mutobvu unoshandiswa pano, unogona kuve nechokwadi chekuti hutano husina kunaka hwainosimudza hapana chekunetsekana nazvo.
Chinhu chakakosha pakubudirira, zvisinei, ndechekuti kana pasina zvakanaka-pitch zvikamu paPCB.Zvikamu zvakaita seBGA uye maSMD hazvina kunaka mune izvi.
3. Durability zvinodiwa
Pamusoro pekuchengetedza mhangura uye zvimwe zvikamu zvakakosha, basa rekurapa kwepamusoro rinofanira kuwedzera pakuvandudza kusimba kwePCB.Iyo yakanyanya kusimba bhodhi inova nekuda kwekushandiswa kwayo, iyo inogara kwenguva refu.
4. Kushandisa uye kushanda
Kushandiswa, kureva kuti bhodhi rakaputirwa nechero ipi yeaya mapedzi richashandiswa, chinhu chakakosha kufunga.Nechikonzero ichi, iyo yekushandisa kana kesi yekushandisa inofanirwa kuverengerwa kubatsira kuita sarudzo yakakodzera.
5. Funga nezvemhoteredzo
Usavhiringe nharaunda nekushandisa kana kesi yekushandisa.Nezvakatipoteredza pano tinoreva rudzi kana nhanho yekufumurwa iyo yakadhindwa yedunhu bhodhi (PCB) ingangove yakafumurwa kana yave yakaputirwa nepamusoro pekupedzisira.
Zvakatipoteredza kazhinji zvinoreva mwero wetembiricha - ingave yakaoma kana kuti yakapfava.Kuti uwane mhedzisiro yakanaka, shandisa HASL inotungamira-isina zvigadzirwa sezvo ichienderana neRoHS, izvo zvinoita kuti ive nehushamwari kune vese mushandisi uye nharaunda yakatenderedza.
6. Sarudza ENIG pamusoro peHASL inotungamira-isina kurapwa kwepamusoro
Iwo matatu (3) makuru sarudzo pamberi pako yePCB yekupedzisa kwepamusoro ndeye HASL, HASL Lead Yemahara uye ENIG.Kunyangwe izvi zvinhu zvitatu zvine zvimiro zvakasiyana, imwe inogona kungova sarudzo iri nani pane imwe.
Chekutanga, iwe unofanirwa kusarudza HASL inotungamira-isina pamusoro peHASL nekuti inoenderana neRoHS, zvinoreva kuti zvinokwanisika kuishandisa kune akasiyana PCB kupera.Icho chokwadi chekuti inopa yakanakisa solderability imwe nzvimbo yekutengesa.
Kune rimwe divi, kana iwe uchida kuchengetedza mari uye kushanda paPCB inoda kuderera tembiricha, saka HASL isarudzo yakanaka.
Kana iwe usina chokwadi kana zvese HASL inotungamira-isina uye HASL ichaita kuti basa riitwe, saka kusarudza electroless nickel kunyudza goridhe (ENIG) ndiyo yakanyanya kunaka sarudzo.Uye zvakare, ENIG ine anenge akafanana hunhu seye lead-isina HASL, senge RoHS inoenderana.
Zhejiang NeoDen Technology Co., Ltd. yave kugadzira nekutumira kunze michina midiki yakasiyana-siyana yekunhonga nenzvimbo kubva muna 2010. Tichitora mukana weR&D yedu yakapfuma ine ruzivo, kugadzirwa kwakanyatsodzidziswa, NeoDen inohwina mukurumbira mukuru kubva kuvatengi vepasi rose.
Isu tinotenda kuti vanhu vakuru uye vatinoshanda navo vanoita NeoDen kambani hombe uye kuti kuzvipira kwedu kune Innovation, Diversity uye Sustainability inovimbisa kuti SMT otomatiki inowanikwa kune wese hobbyist kwese kwese.
