Tisati taunza iyo solder mask hwindo, isu tinofanira kutanga taziva kuti solder mask chii.Solder mask inoreva chikamu chebhodhi rakadhindwa redunhu kuti rive inki, iro rinoshandiswa kuvhara maronda nemhangura kudzivirira zvinhu zvesimbi paPCB uye kudzivirira mapfupi maseketi.Solder mask kuvhura kunoreva kuvhura kuvhura pane solder mask layer kuitira kuti welding iitwe pakuvhurwa.Chero nzvimbo iyo isina solder mask yakadhindwa inogona kunzi kuvhura hwindo.Nzvimbo iyo solder mask haina kudhindwa inosanganisira mapedhi akatengeswa, zvigamba pads, slot chinzvimbo, zvichingodaro.Kune zvakare nyaya inonzi hafu-yakavhurika hwindo.Iyo hafu-yakavhurika hwindo inoreva kuti pad chikamu hachina kuvharwa ne solder mask, uye imwe yakafukidzwa ne solder mask.

一.Nzira yekusiyanisa sei "kuburikidza nepahwindo" uye "kuburikidza nemafuta ekuvhara"

Mazwi ekuti "kuburikidza nehwindo" uye "kuburikidza nemafuta evhavha" anogona kunzwika kazhinji mudhizaini yebhodhi dhizaini.Kutaura zvazviri, zvinoreva kuti mumwe anozarura hwindo kune gomba, uye imwe inovhara gomba nemafuta.Mune mamwe mazwi, kana kuvhara pamusoro pePCB..

Kuvhura hwindozvinoreva kuti inogona kuiswa nyore nyore panzvimbo iyo hwindo rinovhurwa, uye kana kuzarura hwindo kunogona kutongwa maererano kana inogona kuiswa.Oiri yekuvhara inoreva chokwadi chekuti hazvisi nyore kuisa tin panguva yechigamba, iyo inotarirwa nemaitiro.Zvikonzero nei vias inonzwa kuti haina kufukidzwa nemafuta ndeiyi: nekuti solder mask mafuta imvura uye pakati pemaburi haina chinhu, zviri nyore kuti mafuta apinde nemaburi panguva yekubika. iyo solder mask mafuta pane solder mask mhete.Somugumisiro, iyo yero ye vias inoitika.Mamiriro ezvinhu aya ane hukama nekusangana kweiyo solder kuramba mafuta, ovheni uye simba, saka pachava nemamwe mamiriro apo girinhi inogona kuoneka pairi, nepo vamwe vasingakwanisi.

二.Sei tichida kuvhura hwindo remasolder mask?

Kune vias, kana hwindo risina kuvhurwa, inki ye solder mask ichapinda mugomba.Kune mamwe maburi asingade inki plug makomba, zvinofanirwa kuagadzira semaburi.Nokuti kuburikidza-gomba akaiswa zvinoriumba, kana PCB isina solder kuvhura hwindo, zvinoriumba haigoni soldered kubhodhi kazhinji.Aperture kuvhurika harisi basa rekushongedza zviri nyore, asi zvakare rinogona kuyerwa pavias.Solder mask kuvhurika kwemaburi mune dzimwe nzvimbo dzakakosha inogona kushandiswa kuyera vias ine multimeter..

Kune PCB, kana hwindo risina kuvhurwa, kurapwa kwepamusoro hakugone kuitwa, uye hapana kupfapfaidza tini kana welding.

三.Ungavhura sei hwindo re solder mask?

1. Muchigadziro, padhi ichazarura hwindo nekutadza (OVERRIDE: 0.1016mm), kureva kuti, padhi inotaridzirwa nemhangura yemhangura, uye kuwedzera kwekunze ndeye 0.1016mm, uye wave soldering inoiswa tinned.Kuchinja kwekugadzira hakukurudzirwe kuve nechokwadi chekutengesa

2. Nokusingaperi, iyo via hole ichava nehwindo (OVERRIDE: 0.1016mm) mukugadzira, kureva kuti, iyo kuburikidza negomba inoratidzwa kune foil yemhangura, kuwedzera kwekunze ndeye 0.1016mm, uye tini ichashandiswa panguva yekushambadzira kwemafungu.Kana iyo dhizaini iri yekudzivirira vias kubva kune tinning uye kusafumura mhangura, iyo PENTING sarudzo inofanirwa kutariswa mune zvekuwedzera zvivakwa zveVia SOLDER MASK kuvhara iyo via.

3. Mukuwedzera, iyi nheyo inogonawo kushandiswa kune isiri-yemagetsi wiring chete, uye solder mask yakasvibirira mafuta ichazarura hwindo zvakakodzera.Kana iri pamhangura foil trace, inoshandiswa kusimudzira kugona kwepamusoro kweiyo trace, uye inogona kuiswa tinned kana solder.Kana iri pane isiri-yemhangura foil trace, inowanzo gadzirirwa sirika screen kudhindwa kwelogos uye akakosha mavara, anogona kuchengetedza kugadzirwa.
