1. Zvikamu zvakajairwa zvinofanirwa kutarisisa kushivirira kwehukuru hwezvakasiyana-siyana zvevagadziri, zvisingaenzaniswi zvikamu zvinofanirwa kugadzirwa zvinoenderana nehukuru chaihwo hwezvikamu pad graphics uye pad spacing.
2. Magadzirirwo epamusoro-akavimbika wedunhu anofanira kuwedzera solder plate processing, pad width = 1.1 kusvika 1.2 nguva yehupamhi hwezvikamu solder kupera.
3. Yakakwirira-density dhizaini kune software raibhurari yezvikamu zvekugadzirisa padhi saizi.
4. Nharaunda pakati pezvikamu zvakasiyana-siyana, waya, bvunzo dzebvunzo, kuburikidza-gomba, mapadhi uye waya yekubatanidza, solder resistance, nezvimwewo inofanira kugadzirwa maererano nemaitiro akasiyana.
5. Funga nezve reworkability.
6. Funga nezvekupisa kupisa, kuwanda kwepamusoro, kupindira kwe-anti-electromagnetic uye dzimwe nyaya.
7. kuiswa kwezvikamu uye kutungamira kunofanira kugadzirwa maererano nezvinodiwa zve reflow kana wave soldering process.Semuenzaniso, kana uchishandisa reflow soldering process, iyo marongerwo dhizaini yezvikamu zvekufunga kutungamira kwePCB muhovhoni yekuyerera.Paunenge uchishandisa wave soldering muchina, muchina wepamusoro haugone kuiswa PLCC, FP, majoini uye makuru eSOIC zvikamu;kuti uderedze wave shadow effect, kuvandudza kunaka kwewelding, kurongeka kwezvikamu zvakasiyana uye nzvimbo yezvinodikanwa zvakakosha;wave soldering pad graphics dhizaini, rectangular components, SOT, SOP components pad kureba zvinofanirwa kuwedzerwa kuti zvibatane neaviri ekunze SOP Wider mapeya emasolder pads kuti adsorb yakawandisa solder, isingasviki 3.2mm × 1.6mm rectangular components, inogona kukwizwa pazvose zviri zviviri. magumo epadhi 45 ° kugadzirisa, zvichingodaro.
8. Yakadhindwa redunhu bhodhi kugadzira zvakare funga nezvemidziyo.Yakasiyana yekumisikidza muchina dhizaini chimiro, kurongeka, yakadhindwa redunhu bhodhi kutapurirana kwakasiyana, saka kumira kweiyo yakadhindwa redunhu bhodhi gomba nzvimbo, bhenji chiratidzo (Mako) magiraidhi nenzvimbo, yakadhindwa redunhu bhodhi mupendero chimiro, pamwe neyakadhindwa redunhu bhodhi mupendero pedyo. nzvimbo yezvikamu haigoni kuiswa ine zvinodiwa zvakasiyana.Kana iyo wave soldering process ikashandiswa, zvinofanirwawo kufunga nezve process mupendero weakadhindwa wedunhu bhodhi rekutumira cheni inoda kusiiwa.
9. Asi zvakare funga nezvemagwaro ekugadzira anoenderana.
10. kuderedza mari yekugadzira pasi pemamiriro ekuvimbisa kuvimbika.
11. iyo yakafanana yakadhindwa yedunhu bhodhi dhizaini, kushandiswa kwemayuniti kunofanirwa kuenderana.
12. Guta-rakakwenenzverwa musangano uye musangano mumwe-wakatarisana nePrinwe wedunhu redunhu dhizaini zvinodiwa zvakafanana
13. Asi zvakare funga nezvemagwaro ekugadzira anoenderana.
