Guía de compra de sustratos cerámicos DBC: Cómo detectar defectos antes de realizar su pedido

Guía de compra de sustratos cerámicos DBC: Cómo detectar defectos antes de realizar su pedido

La pieza que falla primero en un módulo de potencia no es la más vistosa; es la capa cerámica inferior. Si está abasteciéndose de sustratos cerámicos DBC para módulos de potencia, los defectos ocultos pueden provocar fallos en campo con costes significativos. A continuación, se explica qué se debe verificar primero. Los defectos que realmente causan fallos La mayoría de los problemas en los sustratos DBC se reducen a unos pocos factores reincidentes. A continuación, se detalla el aspecto de cada uno y por qué ocurre: Porosidades (Voids) en la capa de unión Las porosidades son finas burbujas atrapadas entre el cobre y la cerámica durante el proceso de unión. Son comunes en proveedores de menor calidad. Tras unos pocos...

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 […]

Guía de grosor de sustratos DBC y capas de cobre: qué especificar antes de realizar el pedido

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 […]
