1. Square ncoo

Nws feem ntau siv thaum cov khoom sib xyaw rau ntawm cov ntawv luam tawm yog cov kab loj thiab ob peb, thiab cov kab ntawv luam tawm yog qhov yooj yim. Thaum ua tus PCB ntawm tes, siv daim ntaub no yooj yim kom ua tiav

2.Round Pad

Dav siv nyob rau hauv ib leeg-tog thiab ob tog luam cov ntawv luam tawm, cov ntu raug npaj tsis tu ncua. Yog hais tias qhov ntom ntawm lub rooj tsavxwm tso cai, cov ntaub qhwv tau loj dua thiab yuav tsis poob thaum lub sijhawm sib dhos.

3. Island Duab Pad

Kev sib txuas hauv ncoo-rau-ncoo sib txuas. Feem ntau siv nyob rau hauv cov txheej txheem sib luag.

4. Polygon ncoo

Nws yog siv kom paub qhov txawv gaskets nrog cov diam uas tsis sib thooj thiab qhov sib txawv ntawm cov tub sab, uas yooj yim rau kev ua tiav thiab kev sib dhos

5. Oval Padthe Pad muaj thaj chaw txaus los txhim kho kev tiv thaiv kev tiv thaiv, feem ntau siv hauv cov khoom siv hauv ob kab

6.Open-puab ncoo

Txhawm rau kom ntseeg tau tias tom qab yoj soldering, lub qhov ntim rau phau ntawv soldering yuav tsis thaiv los ntawm kev sib tua.

7. Hla phoo

Cov ntaub qhwv uas zoo li cov ntaub qhwv yog tseem hu ua thermal ntaub, thiab lwm yam yog kom txo cov vuam muag lossis tshuaj tiv thaiv tsis tseeb los ntawm tshav kub ntau dhau.

● Thaum koj cov ntaub qhwv hauv av. Cov paj ntoo khaub lig-puab tuaj yeem txo qhov chaw sib txuas ntawm cov xaim hauv av, maj mam ua cua sov dissipation ceev, thiab pab txhawb kev vuam.

● Thaum koj lub PCB xav tau lub tshuab kev tso kawm thiab xav tau lub tshuab puab cuam tshuam, vim tias yuav tsum tau muab tshuaj txhuam ib qho ntxiv)

8. Tearprop ncoo

Nws yog feem ntau siv thaum cov kab txuas txuas rau lub liner yog nyias, kom tiv thaiv cov ntaub qhwv ntawm cov kab thiab qhov tsis sib xws ntawm cov kab ntawv. Cov kab ntawv no feem ntau siv hauv cov hluav taws xob siab ntau
