Gold Plating Factors
Zvido Zvekushandisa
Unofanira kutanga nekufunga nezvekuti uchashandisa sei PCB yako. Mamwe mabhodhi anofanira kugara kwenguva yakareba. Mamwe anoda kubata nekupinza nekubvisira kwakawanda, senge ane edge connectors. Kana ukagadzira bhodhi rekombuta kana sevha, ungangoda hard gold pcb . Rudzi urwu rwegoridhe rinokupa nzvimbo yakasimba. Inoshanda zvakanaka kune zvikamu zvinosakara zvakanyanya.
Kana bhodhi rako richingoda kutakura masaini uye risingatarise zvakanyanya kubata kumeso, unogona kusarudza yakatetepa goridhe plating. Izvi zvinochengetedza mari uye zvichiri kuchengetedza bhodhi rako. Unofanirawo kufunga nezvezvakatipoteredza. Kana PCB yako ichasangana nemwando kana makemikari, iwe unoda goridhe plating inopa yakanaka corrosion resistance.
Zano: Gara uchienzanisa ukobvu hwegoridhe repurasitiki nekushandiswa chaiko kwePCB yako. Izvi zvinokubatsira kudzivirira kushandisa mainjiniya zvakanyanya uye zvinoderedza mitengo.
Kuita uye Kuvimbika
Iwe unoda kuti PCB yako ishande zvakanaka uye igare kwenguva refu. Kuisa goridhe kunokubatsira iwe kuzadzisa zvinangwa zvese. A gobvu layer yegoridhe plating inokupa iwe zvirinani kubata magetsi. Inobatsirawo kudzivirira matambudziko senge oxidation. Kana ukashandisa yakaoma goridhe pcb, unowana zvakatowanda durability. Izvi zvakakosha kune zvibatanidza zvauno plug mukati nekubuda kakawanda.
Mamwe mapuranga anoda kushanda munzvimbo dzakaoma. Muzviitiko izvi, goridhe rakakora rinogona kudzivirira kubva mukukuvadzwa. Inoitawo kuti bhodhi rirambe richishanda kunyange kana nzvimbo yacho ikakwenya. Iwe unofanirwa kugara uchitarisa kana dhizaini yako inoda kuvimbika kwakanyanya. Kana zvikadaro, usatore yakatetepa goridhe plating chete kuti uchengetedze mari.
Mutengo uye Kugadzira
Iwe unofanirwa kuenzanisa kuita nemutengo. Ndarama inodhura. Kana ukashandisa zvakawandisa, mari yepurojekiti yako inokwira nekukurumidza. Iwe unofanirwa chete kushandisa gobvu goridhe plating paunoda chaizvo. Kune akawanda mabhodhi, chiyero chakakora chinoshanda zvakanaka uye chinochengeta mutengo uri pasi pekutonga.
Vagadziri vane miganhu yekuti vanogona kugadzira goridhe rakakora sei kana kuti rakatetepa sei. Kana ukakumbira jira rakakora kwazvo, rinogona kunonoka kugadzirwa kana kukonzera matambudziko nemaitiro acho. Mamwe marudzi egoridhe rakakora, senge goridhe rakaoma, anoda matanho akakosha. Izvi zvinogona kuwedzera mari nenguva inodiwa kugadzira bhodhi rako.
Rondedzero yeKudzora Mutengo:

Solderability
Iwe unoda kuve nechokwadi kuti PCB yako iri nyore kutengesa. Kuisa goridhe kunobatsira nedanho iri. Ukobvu hwakarurama hunoita kuti solder ifambe zvakanaka uye inonamira zvakanaka. Kana iyo goridhe layer yanyanya kutetepa, base simbi inogona kuratidza kuburikidza. Izvi zvinogona kukonzera urombo solder majoini. Kana goridhe rakanyanya kukora, rinogona kuita kuti soldering iome kana kudhura kupfuura zvinodiwa. Iwe unofanirwawo kuyeuka kuti goridhe plating inopa bhodhi rako rakasimba rinopesana nekuora. Izvi zvinochengetedza majoini ako ekutengesa akachengeteka kubva kune unyoro uye makemikari.
Zano: Gara uchienzanisa ukobvu hwegoridhe rekuisa simbi nemaitiro ako ekusonesa kuti uwane mhedzisiro yakanaka.
Typical Ukobvu Ranges
Standard Gold Plating Values
Iwe unofanirwa kuziva zviyero zvakajairwa zvegoridhe plating paPCBs. Miyero yeindasitiri, senge IPC-4556, inokubatsira kusarudza ukobvu chaihwo. Mazhinji egoridhe eplating mhando dzePCBs anowira pakati pe0.03 microns uye 1.0 micron. Iwe kazhinji unoona 0.03-0.05 microns yemasaini mapedhi. Iyi nhete yakatetepa inoshanda zvakanaka kune nzvimbo dzisina kupfeka. Kune edge connectors uye zvigunwe zvegoridhe, iwe kazhinji unoda kuchengetedzwa kwakawanda. Iwe unofanirwa kushandisa 0.76 microns kana kupfuura munzvimbo idzi.
Heino tafura yekukubatsira kuenzanisa ukobvu hwakajairika:
Nzvimbo yePCB | Typical Hukobvu (microns) | Shandisa Nyaya |

Goridhe Yakaoma PCB vs. Kunyudza Goridhe
Une sarudzo mbiri huru yegoridhe yekuisa mhando: yakaoma goridhe pcb uye kunyudza goridhe. Rudzi rumwe norumwe rune mashandisirwo ayo uye makobvu marefu.
A hard gold pcb anoshandisa electroplated gold. Izvi zvinogadzira nzvimbo yakaoma, isingapfeki. Unowanzoona yakaoma goridhe pcb pamupendero connectors uye kuonana pfungwa. Ukobvu hwegoridhe rakaoma pcb kazhinji inotanga pa 0.76 microns uye inogona kuenda kumusoro. Izvi zvinoita kuti ive yakakwana kune nzvimbo dzinotarisana nezvakawanda zveplugging uye unplugging.
Kunyudza goridhe kunoshandisa makemikari maitiro. Mhando iyi inokupa mutete, munyoro. Iwe kazhinji unoona kunyudzwa kwegoridhe pamapadhi epamusoro ekutengesa. Ukobvu hwegoridhe rekunyudza kazhinji hunogara pakati pe0.03 ne0.1 microns. Kunyudzwa goridhe rinoshanda nemazvo kune zvakanaka-pitch zvikamu uye nzvimbo dzaunoda solderability yakanaka.
Heino kuenzanisa nekukurumidza:
