AMB Substrates for Power Modules: What to Check Before You Buy

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 […]

DBC Substrate Thickness and Copper Layer Guide: What to Specify Before You Order

DBC Substrate Thickness and Copper Layer Guide: What to Specify Before You Order

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. […]
