Txawm hais tias tsis muaj qhov sib txawv thaum pom thawj zaug, cov khoom lag luam zoo yuav thaum kawg tsim nyog ntau dua

Nws yog los ntawm qhov chaw uas peb pom qhov sib txawv, uas yog qhov tseem ceeb rau kev ua haujlwm ntev thiab ua haujlwm ntawm PCB nyob rau hauv tag nrho lub neej. Cov neeg siv khoom ib txwm tsis pom qhov sib txawv no, tab sis lawv tuaj yeem tso siab tau tias cov PCBs muab tau ua tau raws li cov qauv nruj tshaj plaws.

Whether in the manufacturing and assembly process or in practical use, PCB should have reliable performance, which is very important. In addition to relevant costs, defects in the assembly process may be brought into the final product by PCB, and faults may occur in the actual use process, resulting in claims. Therefore, from this point of view, it is not too much to say that the cost of a high-quality PCB is negligible.

Hauv txhua ntu kev lag luam, tshwj xeeb tshaj yog cov uas tsim cov khoom lag luam hauv thaj chaw thov tseem ceeb, qhov tshwm sim ntawm qhov ua tsis tiav yog qhov ua tsis tau.

These aspects should be kept in mind when comparing PCB prices. Although the initial cost of reliable, guaranteed and long-life products is high, they are worth it in the long run.
