1. Chii chinonzi PCB Electroplating?
Kuisa simbi muPCB zvinoreva nzira yekuisa simbi pamusoro pePCB kuti pave nekubatana kwemagetsi, kutumira masaini, kudzima kupisa, nezvimwe zvinhu. Kuisa simbi muDC yechinyakare kunosangana nematambudziko akadai sekusakwana kwekufukidza, kusakwana kwekudzikisa simbi, uye mhedzisiro yemupendero, zvichiita kuti zviome kusangana nezvinodiwa zvekugadzira maPCB epamusoro senge mabhodhi eHigh-Density Interconnect (HDI) uye Flexible Printed Circuits (FPC). Zvishandiso zvemagetsi zvinoshandura simba remagetsi epamusoro kuita AC ine frequency yakakwira, iyo inozogadziriswa uye kusefa kuti igadzire DC yakagadzikana kana pulsed current. Mafrequency avo ekushanda anogona kusvika makumi kana mazana e kilohertz, anopfuura simba remagetsi (50/60Hz) emagetsi eDC echinyakare. Hunhu uhwu hwe frequency yakakwira hunounza mabhenefiti akati wandei kuPCB electroplating.
2. Mabhenefiti eHigh-Frequency Switching Power Supplies muPCB Electroplating
Kuvandudzwa Kwekufukidza Kufanana: "Mhedzisiro yeganda" yema "high-frequency currents" inoita kuti magetsi arambe ari pamusoro pemuchina wekufambisa, zvichinyatsovandudza kufanana kwemafuta uye kuderedza mhedzisiro yemupendero. Izvi zvinonyanya kubatsira pakuputira zvivakwa zvakaoma senge mitsetse midiki nemaburi madiki.
Kugona Kwakawedzerwa Kwekuputira Zvakadzika: Mafuremu emvura ane frequency yakakwira anogona kupinda zviri nani mumadziro emaburi, zvichiwedzera ukobvu uye kufanana kwepurasitiki iri mukati memaburi, izvo zvinosangana nezvinodiwa zvepurasitiki zvemavhiya ane aspect ratio yepamusoro.
Kuwedzera Kushanda Nemagetsi: Hunhu hwekukurumidza kupindura kwemagetsi ekushandura ma frequency akawanda hunogonesa kudzora magetsi kwakanyatsojeka, kuderedza nguva yekuputira uye kuwedzera kushanda zvakanaka kwekugadzira.
Kuderedzwa Kwesimba Rinoshandiswa: Simba rinoshanduka-shanduka rine simba rakawanda uye simba shoma rinoshandiswa, zvichienderana nemaitiro ekugadzira zvinhu zvakasvibira.
Kugona Kuisa Pulse Plating: Simba remagetsi rinochinja-chinja rinogona kuburitsa pulsed current zviri nyore, zvichiita kuti pulse electroplating ishande zvakanaka. Kuisa pulse plating kunovandudza kunaka kwe coating, kunowedzera coating density, kunoderedza porosity, uye kunoderedza kushandiswa kwezvimwe zvinowedzera.
3. Mienzaniso yeMashandisirwo Emagetsi Anoshandiswa Pakuchinja Mazhinji muPCB Electroplating
A. Kuisa Copper Plating: Kuisa copper electroplating kunoshandiswa mukugadzira PCB kugadzira jira rinofambisa mhepo redunhu. Zvigadziriso zvekuchinja-chinja zvine frequency high-frequency zvinopa huwandu hwemagetsi chaiwo, zvichiita kuti jira remhangura rive rakafanana uye zvinovandudza kunaka uye mashandiro ejira rakaiswa.
B. Kurapa Pamusoro: Kurapa pamusoro pePCBs, senge goridhe kana sirivheri, kunodawo simba rakasimba reDC. Zvigadziriso zvekuchinja-chinja zvine frequency high-frequency zvinogona kupa magetsi akakodzera uye voltage yesimbi dzakasiyana dzeplating, zvichiita kuti coating irambe yakatsetseka uye ichiramba ngura.
C. Kuisa Makemikari: kuisa machemikari kunoitwa pasina magetsi, asi maitiro acho ane zvinodiwa zvakasimba zvekupisa uye huwandu hwemagetsi. Magadzirirwo ekuchinja-chinja ane frequency yakakwira anogona kupa simba rekubatsira pakuita uku, zvichibatsira kudzora mwero wekuisa machemikari.
4. Maitiro Ekuona Maitiro Ekushandisa Simba rePCB Electroplating
Zvinodiwa pakushandisa magetsi eDC pakugadzira magetsi ePCB zvinoenderana nezvinhu zvakati wandei, kusanganisira rudzi rwemagadzirirwo emagetsi, saizi yePCB, nzvimbo yekuputira, zvinodiwa pahuwandu hwemagetsi aripo, uye kushanda zvakanaka kwekugadzira. Heano mamwe ma parameter akakosha uye ma specifications akafanana emagetsi:
A. Magadzirirwo Azvino
●Kuwanda Kwazvino: Kuwanda kwazvino kwePCB electroplating kunowanzova pakati pe1-10 A/dm² (ampere pa square decimeter), zvichienderana nemaitiro e electroplating (semuenzaniso, copper plating, gold plating, nickel plating) uye zvinodiwa pakuputira.
●Zvinodiwa Pari Zvino: Zvinodiwa pari zvino zvose zvinoverengwa zvichienderana nenzvimbo yePCB uye huwandu hwezvino. Semuenzaniso:
⬛Kana nzvimbo yePCB plating iri 10 dm² uye density yemazuva ano iri 2 A/dm², huwandu hwese hwemagetsi hunodiwa huchava 20 A.
⬛Kune maPCB makuru kana kugadzirwa kwemagetsi akawanda, mazana emaampere kana kuti magetsi akakwira anogona kudiwa.
MaRanges Akajairika Emazuva Ano:
●MaPCB madiki kana kushandiswa murabhoritari: 10-50 A
●Kugadzirwa kwePCB yepakati nepakati: 50-200 A
●MaPCB makuru kana kugadzirwa kwakawanda: 200-1000 A kana kupfuura
Magadzirirwo eB.Voltage
Kuisa ma electroplating ePCB kunowanzoda ma voltage akaderera, kazhinji ari pakati pe 5-24 V.
⬛Zvinodiwa pamagetsi zvinoenderana nezvinhu zvakaita sekudzivirira kwebhavhu rekuputira, daro riri pakati pemaelectrode, uye kufambisa kwemagetsi.
⬛Kune maitiro akasarudzika (semuenzaniso, pulse plating), magetsi akakwira (akadai se30-50 V) anogona kudiwa.
Magadzirirwo Emagetsi Akajairika:
●Kuisa magetsi muDC kwakajairika: 6-12 V
●Kuputira mapuroteni kana maitiro akasarudzika: 12-24 V kana kupfuura
Mhando dzeMagetsi
●Kupa Simba reDC: Rinoshandiswa pakushandisa magetsi eDC, richipa simba remagetsi nemagetsi zvakagadzikana.
●Kupa Simba rePulse: Rinoshandiswa pakuisa ma electroplating epulse, rinokwanisa kuburitsa ma pulsed currents ane frequency yakakwira kuti rivandudze kunaka kwekuisa ma plating.
●Magetsi Ekuchinja Anoshanda Kakawanda: Kushanda nesimba uye kupindura nekukurumidza, zvakakodzera zvinodiwa zve electroplating zvine hungwaru.
C.Simba reKupa Simba
Simba remagetsi (P) rinotsanangurwa nemagetsi (I) uye voltage (V), nefomura: P = I × V.
Semuenzaniso, simba rinoburitsa 100 A pa12 V rinenge riine simba re1200 W (1.2 kW).
Simba Rakafanana:
●Midziyo midiki: 500 W - 2 kW
●Midziyo yepakati nepakati: 2 kW - 10 kW
●Midziyo mikuru: 10 kW - 50 kW kana kupfuura
Nguva yekutumira: Kukadzi-13-2025
