在我們的日常生活和工作中,電子設(shè)備和各種儀器已經(jīng)悄然融入我們的身邊。而我們?cè)絹?lái)越離不開(kāi)它們,它們已經(jīng)成為日常生活的必需品。如電腦、手機(jī)、Ipad等。這些元件的核心是pcb。也統(tǒng)稱為電路板,PCB是PCBA加工后的。在pcb生產(chǎn)加工之前,首先要設(shè)計(jì)PCBA的加工方案。以下是主要的打樣方法!   1.減去法?!?

要想在一塊小小的電路板上實(shí)現(xiàn)多功能操作,僅僅依靠裸露的PCB是沒(méi)有辦法完成的。必須將元件安裝在裸露的PCB上,并焊接插件。這些技術(shù)流程被稱為PCBA加工。 PCBA加工與PCB的區(qū)別在于,不經(jīng)過(guò)任何處理的印刷電路板稱為PCB裸板,而PCBA是指在PCB裸板上焊接電子元器件的全過(guò)程。 就工藝而……

SMT貼片加工作為高精技術(shù),對(duì)工藝要求也非常嚴(yán)格。許多現(xiàn)代電子產(chǎn)品的SMT元器件的尺寸趨向于小型化。除了SMT元器件越來(lái)越小和精致之外,高靈敏度元器件對(duì)加工環(huán)境的要求也越來(lái)越高。下面簡(jiǎn)單介紹一下SMT貼片加工的注意事項(xiàng):   第一點(diǎn):錫膏冷藏   剛買(mǎi)回來(lái)焊錫膏,如果我不馬上用,需要把它放在冰箱里冷藏。溫度應(yīng)保持在5℃-0℃,不低于0℃。關(guān)于錫膏的攪拌使用,網(wǎng)上有很多解釋,這里就不介紹了。   第二點(diǎn):及時(shí)更換貼片機(jī)耗材。   在貼片機(jī)生產(chǎn)過(guò)程中,由

今天PCBA一站式服務(wù)廠家給大家講講PCBA打樣為什么成本更高?PCBA打樣成本計(jì)算方法。電子產(chǎn)品開(kāi)發(fā)商在PCBA量產(chǎn)前會(huì)有一個(gè)PCBA打樣確認(rèn)階段。PCBA打樣的數(shù)量通常在5到5-20個(gè)之間。經(jīng)歷過(guò)PCBA打樣的人都會(huì)知道PCBA打樣的平均單價(jià)很高,那么高的成本在哪里呢?接下來(lái),PCBA一站式服務(wù)廠的領(lǐng)導(dǎo)將向您解釋?!?

PCBA代工代料是什么? 廣義的PCBA代工代料指供給電子元器件代購(gòu)及PCBA加工的效勞。廣義的PCBA代工代料指供給從電子計(jì)劃備案、電子產(chǎn)物開(kāi)拓到物料代購(gòu)、樣本打樣嘗試、后期批量加工消費(fèi)的一整套PCBA加工效勞。 怎樣去選PCBA代工代料廠家? 一、存戶采用PCBA代工代料廠家的功夫,須要對(duì)其基礎(chǔ)情景舉行刻意參觀,更加是必需要核實(shí)我廠家的正軌性和專科性。對(duì)于其正軌性,大師不妨從其關(guān)系天性舉行領(lǐng)會(huì),比方能否經(jīng)過(guò)ISO9001品質(zhì)處置體制認(rèn)證等;對(duì)其電子加工??菩缘念I(lǐng)會(huì),就須要越發(fā)細(xì)心少許

一、框架和鋼網(wǎng)的尺寸   在PCBA一站式服務(wù)之前,為了使印刷越發(fā)完備和符合,須要定制安排的鋼網(wǎng)。鋼網(wǎng)最要害的是鋼網(wǎng)的尺寸和框架。鋼網(wǎng)沿用ab膠和尼龍網(wǎng)紗的拉伸辦法,必需在鋁框和膠水的接縫處平均地刮一層養(yǎng)護(hù)漆(s224)。為保護(hù)鋼網(wǎng)有充滿的張力(規(guī)則大于35n/cm,普遍訴求30~50n/cm)和杰出的平坦度,訴……
