What are the important processes for PCBA proofing of ceramic substrates?

2022-01-08

在PCBA打樣中，與玻璃纖維板相比，陶瓷基板容易破碎，對工藝要求更高。陶瓷基板打樣過程中有幾個非常重要的技術(shù)環(huán)節(jié)。讓雷卡仕來分享一下: 　　1.鉆孔　　通常，陶瓷基板通過激光鉆孔。與傳統(tǒng)鉆孔技術(shù)相比，激光鉆孔技術(shù)具有精度高、速度快、效率高、可大規(guī)模批量鉆孔、適用于大多數(shù)軟硬材料、不損耗工具……

PCBA加工對焊接切邊和溫度有什么要求？

2021-12-21

一般來說，PCBA加工需要選擇無塵防靜電的車間，溫濕度有控制目標(biāo)，對切腳沒有要求。　　對于貼片加工來說，掌握焊接溫度非常重要。一般來說，手工焊接溫度應(yīng)保持在240-280度的標(biāo)準(zhǔn)范圍內(nèi)，設(shè)定溫度與烙鐵溫度的差值應(yīng)盡可能小。　　如果設(shè)備的焊接預(yù)熱區(qū)、保溫區(qū)、回流焊區(qū)、冷卻區(qū)不同，就要根據(jù)不……
