Mitundu ya PCB pads

1. Square pad

Nthawi zambiri amagwiritsidwa ntchito pamene zigawo zomwe zili pa bolodi losindikizidwa zimakhala zazikulu komanso zochepa, ndipo mzere wosindikizidwa ndi wosavuta. Mukamapanga PCB ndi dzanja, kugwiritsa ntchito pedi iyi ndikosavuta kukwaniritsa

2. Pepala lozungulira

Amagwiritsidwa ntchito kwambiri mu matabwa a mbali imodzi ndi awiri osindikizidwa, zigawozo zimakonzedwa nthawi zonse. Ngati kachulukidwe ka bolodi kamalola, mapadi amatha kukhala okulirapo ndipo sangagwe panthawi ya soldering.

3. Chilumba cha mawonekedwe

Malumikizidwe a pad-to-pad amaphatikizidwa. Amagwiritsidwa ntchito kwambiri pakuyika kokhazikika kosakhazikika.

4. Polygon Pad

Amagwiritsidwa ntchito kusiyanitsa ma gaskets omwe ali ndi ma diameter ofanana akunja ndi ma diameter osiyanasiyana a dzenje, omwe ndi abwino kuti azitha kukonza ndikusonkhanitsa.

5. Oval PadPad ili ndi malo okwanira kupititsa patsogolo luso loletsa kuvula, lomwe nthawi zambiri limagwiritsidwa ntchito pazida zapawiri.

6.Open-woboola Padi

Pofuna kuwonetsetsa kuti pambuyo pa kutenthedwa kwa mafunde, mabowo a pad soldering pamanja sangatsekedwe ndi solder.

7. mtanda PAD

Mapadi opangidwa ndi mtanda amatchedwanso mapepala otentha, mapepala otentha otentha, etc. Ntchito yake ndi kuchepetsa kutentha kwa mbale yowotcherera panthawi yowotcherera, ndikupewa kuwotcherera zabodza kapena PCB peeling chifukwa cha kutentha kwambiri.

● Mukapukuta mapepala anu. Duwa lopangidwa ndi mtanda limatha kuchepetsa malo olumikizirana ndi waya wapansi, kuchepetsa kuthamanga kwa kutentha, ndikuthandizira kuwotcherera.

● Pamene PCB yanu ikufuna makina oyika makina ndipo ikusowa makina opangira reflow soldering, pad yoboola pakati ingalepheretse PCB kusweka (chifukwa kutentha kwakukulu kumafunika kusungunula phala la solder)

8. gwero la misozi

Nthawi zambiri amagwiritsidwa ntchito ngati mzere womwe umalumikizidwa pa lineryo uli woonda, kuti apewe kusenda kwa liner ndi kuchotsedwa kwa chingwecho. Liner iyi nthawi zambiri imagwiritsidwa ntchito pamayendedwe apamwamba kwambiri
