Bɔku tin dɛn de we yu fɔ tink bɔt we yu de disayn di pafɛkt PCBA

Fɔ disayn wan pafɛkt PCBA (Printed Circuit Board Assembly) nid fɔ tink bɔt bɔku tin dɛn, frɔm di sakit dizayn to di kɔmpɔnɛnt sɛlɛkshɔn, to prodakshɔn ɛn tɛst. Dis na sɔm prɔblɛm dɛn, di men pɔynt dɛn na PCBA dizayn ɛn di we dɛn fɔ ajɔst pafɛkt dizayn.

1. Difikulti dɛn na PCBA dizayn

Sakit Kɔmplisiti: Di ilɛktronik tin dɛn we dɛn de yuz tide de gɛt mɔ ɛn mɔ pawa, ɛn dis de mek dɛn de mek kɔmpleks sakit dizayn dɛn. Bɔku layers bod dɛn, ay-spid signal dɛn, miks signal dɛn (analɔg ɛn dijital), ɛn ɔda tin dɛn go mek i nɔ izi fɔ dizayn.

Tɛmral manejmɛnt: Di kɔmpɔnɛnt dɛn we gɛt ay pawa go mek bɔku ɔt If di ɔt nɔ go ebul fɔ pul di ɔt fayn fayn wan, i go mek PCBA pefɔmɛns pwɛl ɔ i go pwɛl.

Ilɛktromagnetik kɔmpatibiliti (EMC): Ilɛktronik ikwipmɛnt nid fɔ mit difrɛn ilɛktromagnetik kɔmpatibiliti standad dɛn, ɛn ilɛktromagnetik intafɛreshɔn (EMI) ɛn ilɛktromagnetik susɛptibiliti (EMS) nid fɔ kɔntrol insay di dizayn.

Spays limiteshɔn: Ɛspɛshali insay miniaturized ilɛktronik prodak, di PCB eria limited, ɛn aw fɔ arenj komponent ɛn trays na di limited spes na chalenj.

Manufakchurin prɔses: Difrɛn manufakchurin prɔses dɛn gɛt difrɛn rikwaymɛnt fɔ dizayn, lɛk di kɔmbaynshɔn fɔ sɔfayz mawnt tɛknɔlɔji (SMT) ɛn tru-hol teknɔlɔji (THT).
