Parizvino, kune marudzi maviri pcb bhodhi kumucheto dhizaini: simbi uye isiri-metallization. Kune isiri-metallization, vagadziri muindasitiri vakura, asi iyo metallization tekinoroji ichiri idiki. Mazuva ano, zvakawanda zvekugadzira zvinodiwa nevatengi zviri kutendeukira kuPCB simbi edging . Naizvozvo, kunaka kwePCB simbi edging kwave kutarisisa kwevatengi 'uye vagadziri 'kutarisisa nekuti mhando yayo inokanganisa zvakananga kushandiswa kwezvigadzirwa.

 Ndeapi mashandisirwo eedge plating muPCB?

Edge plating wedunhu mabhodhi akajairika mumaindasitiri mazhinji, uye kupendeka kwemupendero chinhu chakajairika. Iwe uchawana PCB kumucheto castellation (kana mupendero plating PCBs) inoshandiswa mune dzakawanda zviitiko, kusanganisira:

· Kuvandudza kugona-kutakura kwazvino

· Edge kubatana uye kudzivirira

· Edge soldering kuvandudza kugadzirwa

· Tsigiro iri nani yekubatanidza semabhodhi anotsvedza mumakesi esimbi

Ndeipi maitiro ePCB edge plating?

Sezvaunoziva, kune akawanda matambudziko emugadziri wePCB yakawanda kunyanya mukugadzirisa mapeche akachekwa uye kunamatira kwehupenyu hwezvinhu zvakapetwa, chii chakanyanya, inoda iyo chaiyo kubata mukugadzira PCB iyo inoshandiswa kumucheto. PCB solder. Isu tinogona kuve nechokwadi chekuti PCB kumucheto castellation inonyatso gadzirira edges nzvimbo, iyo inoshandisa iyo yakapfava mhangura yekukasira kunamatira uye inogadzirisa bhodhi redunhu kuti ive nechokwadi chekunamira kwenguva refu pakati pega rega rega.

Hazvina maturo kutaura, isu tinogona kudzora njodzi inogona kuitika yekuputirwa neburi uye kumucheto plating ine inodzorwa maitiro panguva yakadhindwa yedunhu bhodhi kugadzira kumucheto soldering. Saka chinonyanya kukosha ndechekusikwa kwemaburrs, izvo zvinoita kuti discontinuities inoputirwa kuburikidza negomba madziro uye inodzikamisa hupenyu hwekunamatira kwekumucheto plating.

Iwo ekunze contours, kuti isimbiswe, inofanira kugayiwa isati yapfuura-gomba plating process, sezvo metallization yemupendero inoitika panguva iyi yekugadzira nhanho. Mushure mekuiswa kwemhangura, iyo inotarirwa pamusoro pekupedzisira inozoiswa kumicheto.

Nyaya dzekugadzira:

1. Copper Peeling -Kuputira pamusoro penzvimbo yakakura ye substrate kunogona kutungamirira kune yakaputirwa mhangura yakasvibiswa nekuda kwekushayikwa kwesimba rekunamatira. Isu tinogadzirisa izvi nekutanga roughening pamusoro kuburikidza nemusanganiswa wemakemikari uye dzimwe nzira dzevaridzi. Tevere, isu tinoshandisa yakananga metallization, iyo ine yakakwira copper bond simba, kugadzirira pamusoro peplating.

2. Burrs -Kakawanda edge plating, kunyanya pamakomba e-castellation, inogona kukonzera mabhura kubva kumagumo ekugadzirisa machining. Isu tinoshandisa yakagadziridzwa, yevaridzi process kuyerera inoita kuti mabhura akwenenzverwe kusvika kumucheto kwechinhu.

Fab Note:

1. Nzvimbo yeantenna yepedhi yegoridhe yakakurisa, inokanganisa kutengesa kwevatengi kana kufambisa kwemasaini.

2. Mupendero wemukati wemukati wakabatanidzwa kune waya pabhodhi, zvichiita kuti ive pfupi pfupi.

3. Gomba rechitambi rakagadzirirwa pa edging groove uye rinofanira kubatwa mu 2nd drilling process.

4. Kuburikidza nekugadzirisa-kwakabatana nekugadzirwa kwePCB yega yega sepaneti, kuenderera mberi kwesimbi yekunze kwekunze hakugoneki. Hapana metallization inogona kuiswa panowanikwa mabhiriji madiki.

5. Chikumbiro chimwe chete, slide plating metallization inogona kuvharwa ne solder mask.

Paunenge uchitenga mapuranga ekumucheto, unofanirwa kusimbisa nemutengesi wako wePCB mukana wekugadzira maPCB ane plating process, uye kusvika papi iyo mugadziri anogona kupinza ndiro PCB. Mafaira ako eGerber kana kudhirowa kwejira kunofanirwa kuratidza mune yemakanika layer kwavanoda masiraidhi plating, uye kupera kwepamusoro kwavanoda pairi. Vazhinji vagadziri vanosarudza yakasarudzika ENIG seyo yega yekupedza yepamusoro yakakodzera kutenderera castlelation.

YMS Electronics Co., Ltd. inyanzvi inogadzira yakakwirira-chaiyo multilayer edunhu mabhodhi, module kunyudza goridhe redunhu mabhodhi, mota dzedunhu bhodhi, kutyaira rekodha, COB magetsi emagetsi, makomputa mamaboard, ekurapa edunhu mabhodhi, module bonding board, bofu buri impedance. bhodhi, thermoelectric separation copper substrate, etc. RayMing inopa yepamusoro-notch kuvimbiswa kwehutano uye kutakura nguva, bhizinesi repamusoro-soro rine kutengesa zvachose. Kana pane kudiwa kwemativi-akavharidzirwa egoridhe mabhodhi, ndapota inzwa wakasununguka kutibata nesu!
