L-applikazzjoni ta ‘ PCB bord is familiar to everyone and can be seen in almost all electronic products. The development of science and technology promotes the growth of PCB circuit board industry, and people have higher and higher requirements for layers, precision and reliability of components. There are many kinds of PCB circuit boards in the market, and it is difficult to distinguish the quality. In this regard, the following to teach you a few ways to identify the PCB circuit board.

L-ewwel, tiġġudika mid-dehra

1. Dehra tal-weldjatura

Minħabba li hemm ħafna partijiet tal-PCB, jekk l-iwweldjar mhux tajjeb, il-partijiet tal-PCB jaqgħu faċilment, li jaffettwa serjament il-kwalità tal-iwweldjar u d-dehra tal-PCB. Għalhekk, huwa importanti ħafna li tissaldja sew.

Regoli standard għad-dimensjonijiet u l-ħxuna

Minħabba li l-bord tal-PCB għandu ħxuna differenti għall-bord standard tal-PCB, l-utenti jistgħu jkejlu u jivverifikaw skont il-ħtiġijiet tagħhom stess.

3. Dawl u kulur

Normalment il-bord tal-PCB estern ikun mgħotti bil-linka biex jaqdi r-rwol ta ‘insulazzjoni, jekk il-kulur tal-bord ma jkunx qawwi, inqas linka, li tindika li l-bord tal-insulazzjoni nnifsu mhux tajjeb.

Two, from the plate to judge

1. Il-kartun HB ordinarju huwa rħis u faċli biex isir deformazzjoni u ksur, u għalhekk jista ‘biss jagħmel pannell wieħed. Il-kulur tal-wiċċ tal-komponent huwa isfar skur, b’riħa eċċitanti, u l-kisja tar-ram hija ħarxa u rqiqa.

2, 94V0 wieħed, bord CEM-1, il-prezz huwa relattivament ogħla mill-bord, il-kulur tal-wiċċ tal-komponent huwa isfar ċar, prinċipalment użat għal bordijiet industrijali u bordijiet tal-enerġija b’rekwiżiti ta ‘klassifikazzjoni tan-nar.

3. Glass fiber board has high cost, good strength and green double-sided. Basically, most PCB boards are made of this material. No matter what color of PCB printing ink to smooth, can not have false copper and bubbling phenomenon.

Knowing the above points, it is not a particularly difficult thing to identify the PCB circuit board.
