당신을 위한 가치 있는 기술 세라믹 콘텐츠!
파워 모듈에서 가장 먼저 고장 나는 부품은 눈에 띄는 상부 부품이 아니라 그 아래에 있는 세라믹 층입니다. 파워 모듈용 DBC 세라믹 기판을 구매할 때 숨겨진 결함은 현장 고장으로 이어져 상당한 비용 손실을 발생시킬 수 있습니다. 우선적으로 확인해야 할 사항을 설명해 드립니다. 실제 고장을 유발하는 결함 DBC 기판 문제의 대부분은 몇 가지 반복적인 결함으로 귀결됩니다. 각 결함의 형태와 발생 원인은 다음과 같습니다. 접합층 내 기포(Voids) 기포(Voids)는 접합 과정에서 구리와 세라믹 사이에 갇히는 미세한 공기방울입니다. 이는 품질 수준이 낮은 공급업체에서 흔히 발생합니다. 단 몇 차례의...

Buying AMB substrate? Choose the wrong supplier and you’re in trouble in the field. This guide has 7 checks before you order. Check: in-house bonding, certifications, capacity, quality control, material options, pricing details, and facility readiness. Do this right. Don’t make costly errors later. What You Should Check Before You Pick a Supplier A datasheet provides you with the numbers. It will not give you an answer as to whether the supplier can maintain the same quality with batch 500 as they did with batch 1. Here are some questions to ask in its place. Does the Supplier Bond […]

Struggling to balance thermal dissipation with high-voltage isolation? You can’t make the difficult compromises with off-the-shelf DBCs, because the ceramic is too thick for your thermal budget or the copper is too thin for your current ratings. You need this technical framework to define custom DBC substrates to exactly meet your power module’s electrical and thermal requirements. What Is a DBC Ceramic Substrate? A DBC substrate is different than a conventional printed circuit board as it is a combination of copper foil that is bonded to a ceramic base without any adhesives or solder between the copper and the ceramic. […]

You are procuring substrates to a power module and you must get it correct. This guide will take you through the DBC ceramic substrate manufacturing process, assist you select the correct ceramic material and what to look at before selecting a direct bonded copper substrate supplier. What Is a Direct Bonded Copper (DBC) Ceramic Substrate? A direct bonded copper (DBC) substrate is a substrate that bonds copper foil to a ceramic base - no adhesives, no solder, nothing in between. You have good thermal conductivity, solid mechanical strength, and electrical insulation all in a single package. This is why DBC […]
