Chigadziko chemasiki chinosungirirwa paPCB chinoreva chikamu chebhodhi chakafukidzwa neingi yegirini inosungirirwa. Nzvimbo dzine maburi emasiki anosungirirwa dzinosiyiwa dzisina inki, zvichiita kuti mhangura ionekwe kuti ishandiswe pakugadzirisa pamusoro uye kusanganisa zvinhu. Nzvimbo dzisina maburi dzinofukidzwa neingi yemasiki inosungirirwa kudzivirira kuoxidation nekubuda kwemvura.
Zvikonzero Zvitatu zveSolder Mask Kuvhurwa:
1. Kuburikidza neHole Pad Kuvhurwa:
Kuburikidza neburi-mapadhi anoda solder mask kuvhurwa. Pasina aya mazaru, mapeji ekutengesa achavharwa neingi, zvichiita kuti zvisaite solder chikamu chinotungamira.
2. SMD Pad Openings:
Solder mask kuvhurwa kunodiwa kune SMD pads kubvumidza soldering. Kana iyo soldering nzvimbo isina mazaru, mapedhi achavharwa neingi, zvinobudirira kuita kuti asashandise.
3. Nzvimbo Yakakura Yemhangura Inovhurwa:
Kuti uwedzere huwandu hwazvino pasina kuwedzera kuteedzera, dzimwe nzvimbo dzine tin-plated. Tin-plating inoda solder mask kuvhurwa munzvimbo idzi.
Nei Solder Mask Kuvhurwa Kwakakura Kune Mapadhi
Maburi emasiki anosungirirwa anowanzo kuve akakura kupfuura mapedhi zvichireva kuti anochinjika pakugadzirwa. Kana kuvhura mask inosungirirwa kwakaenzana nepedhi, kusiyana kwekugadzirwa kunogona kukonzera kuti inki inofukidza chikamu chepedhi. Kuti izvi zvisaitike, maburi emasiki anosungirirwa anowanzo wedzerwa ne4-6 mils kupfuura saizi yepedhi, tichifunga nezvemaitiro ePCB ekugadzira.
Zvikonzero zveSolder Mask Omission
1. Gerber Faira Zvikanganiso:
Munguva yekugadzira maitiro, mugadziri anogona netsaona kusiya solder mask kuvhurika muGerber faira nekuda kwezvisizvo zvigadziriso kana kukanganisa. Kana iyo solder mask layer isina kurongeka zvakanaka kuti ibatanidze kuvhurika kwepadhi panguva yekubuda kweGerber, iyo inoguma faira inoshaya mazaruro anodiwa.
2. Zvisizvo Package Dhizaini:
Zvikanganiso mukugadzirwa kwePCB package zvinogona kukonzera kushaikwa kwemaopenings emasiki esolder. Mhinduro ndeyekugadzirisa maproperties epad nemazvo. Mupad stack manager, wedzera Soldermask Top (kana Bottom ) uye gadzirisa chimiro cheSoldermask kuti uwane open yaunoda.
3. Kusapindirana kweSoftware Version:
Kusiyana kuripo pakati peshanduro dzesoftware dzeEDA kunogona kukonzera kusashanda kwemask ekusolder. Semuenzaniso, kushandisa software yeAD ine mhando yepamusoro uko mapad anotsanangurwa uchishandisa basa reTrack kunogona kukonzera matambudziko kana faira reGerber rikavhurwa mumhando yakaderera. Mushanduro dzekare, matrack haagadzire maburi emask ekusolder, nepo software yeAD ine mhando yepamusoro inopa mahunhu akakosha kumatrack.
4. Zvisizvo Via Attributes:
Musoftware yeAD, kuwedzera mapedhi uchishandisa VIA pachinzvimbo chePAD kunogona kukonzera matambudziko emasiki ekusolder. MaVias anowanzo kuve nemasiki ekusolder asina kugadzirwa nemaoko kunze kwekunge akagadzirwa neimwe nzira. Kana mavias anoda maburi ekusolder mask akawedzerwa zvisirizvo, anogona kuvharwa panguva yekugadzira.
5. Mafaira ekugadzirisa:
Panguva yekudzokorora zvigadziriso, kugadzirisazve, kana kukopa faira rebhodhi, kuvhurika kwemasiki ekutengesa kunogona kubviswa netsaona nekuda kwekukanganisa kwemushandisi, zvichikonzera kushaikwa kwekuvhurwa mudhizaini yekupedzisira uye kudzivirira kushambadzira kwakaringana.
Nekugadzirisa izvi zvinokonzeresa uye nekutevera kwakaringana magadzirirwo maitiro, solder mask kusiiwa muPCB magadzirirwo anogona kudzikiswa, kuve nechokwadi chekutengesa kwakavimbika uye kushanda.
