Costs incurred in the process of PCBA OEM and material procurement. Some costs are visible, that is, costs that are easier to analyze or can be derived directly from financial statements; some are invisible, that is, those that are difficult to analyze or

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。……

With the development of science and technology, many electronic products are developing in the direction of miniaturization and refinement, which makes the size of many SMD components smaller and smaller. Not only the requirements for the processing envir

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?？菩?。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……

SMT patch processing refers to attaching components to a PCB printed with glue or solder paste through a placement machine, and then soldering through reflow soldering. SMT chip processing is highly praised by electronic product customers for its advantag

With the development of science and technology, many electronic products are developing in a small and refined direction, which makes the size of many SMD components smaller and smaller. Not only the requirements for the processing environment continue to
