最初SMT鋼網的(de)制造過程主要是照(zhào)相(xiàng)制闆,然後再通(tōng)過采用化(huà)學腐蝕加工(gōng)法。當然還(hái)有(yǒu)采用激光(guāng)切割加工(gōng)法或者電(diàn)鑄加工(gōng)法來(lái)對(duì)SMT鋼網的(de)制闆進行加工(gōng)。
PCB線路(lù)闆為(wèi)什麽要做阻抗?PCB線路(lù)闆阻抗是指電(diàn)阻和(hé)對(duì)電(diàn)抗的(de)參數,對(duì)交流電(diàn)所起着阻礙作(zuò)用。在PCB線路(lù)闆生(shēng)産中,阻抗處理(lǐ)是必不可少的(de)。
在現(xiàn)在經濟高(gāo)速發達的(de)階段裏,線性模組的(de)使用變得越來(lái)越普遍,而且越發的(de)重要,在我們的(de)日(rì)常生(shēng)活中,但(dàn)是有(yǒu)很(hěn)多人(rén)都(dōu)不知道(dào)如何去(qù)選擇線性模組。
每一個(gè)機(jī)械産品的(de)特點很(hěn)多都(dōu)會來(lái)自(zì)它不同的(de)因素取決,可能是因為(wèi)它的(de)整體(tǐ)安裝工(gōng)藝,也可能是因為(wèi)它的(de)配件(jiàn),同樣也會它的(de)外(wài)部驅動構件(jiàn)影響。促成一個(gè)機(jī)械産品擁有(yǒu)這(zhè)個(gè)特點可以說(shuō)有(yǒu)很(hěn)多種可能性。
Interview: With the rapid advancement of the China Manufacturing 2025 Program and the prevalence of the Industry 4.0 concept, the world is gradually moving from the information age to the intelligent era of the Internet of Everything, and various traditional industries are undergoing intelligent upgrades while consumers The functional requirements for terminal electronic products are also becoming more and more abundant.
What is the current status and development trend of domestic medical device companies? China's medical device industry has a low concentration, and most medical device companies are small in scale, and can only produce low-end products. High-end products can only be looked up. However, due to the huge demand in the downstream market, high-end products can only rely on imports.
