Comparison of several PCB surface finish typesAs for the essential proceed in PCB production, the basic purpose of surface treatment is to ensure good solderability or electrical properties. Since copper in nature tends to exist in the form of oxides in the air, it is unlikely to re...
PCB Via-in-PadWhen it comes to Vias, it’s known to us all that Vias can be divided into Through-hole Vias, Blind Vias and Buried Vias. They have different functions.With the development of the electronic products, Vias play a vital role in the interconnection between layers in a...
There are two wire bonding processes that are used,Thermosonic (T S)Gold Ball Wire BondingandUltrasonic (U S)Aluminum Wedge Wire Bonding Approximately 90% of all IC Assembly in Semiconductor Packages is manufactured using Gold Ball Bonding process, while Aluminum Wedge Bonding is used to
WHAT IS RIGID-FLEX PCB?Rigid-flex PCB is a printed circuit consisting of both flexible circuit and rigid circuit This combination is ideal for exploiting the benefits of both flexible and rigid circuits - the rigid circuits can carry all or the bulk of the components, with the flexi
