PCB layout is PCB design.PCB design needs to be realized by computer aided design. The commonly used design software in the industry is cadence Allegro, pads, Altium designer. Conventional PCB design includes several steps, such as database building, network adjustment table, layout, wiring, file output, etc., but the conventional PCB design process is far from…
1. Multilayer flexible PCB raw materials (1) It is divided into glued materials and glue less materials. The copper on the material is divided into copper and calendared copper, and the material without rubber and copper is better in flexibility and folding. (2) Thickness of material: PI+ copper thickness 2. Multilayer flexible PCB cover film…
A Multilayer Flexible Printed Circuit Board (FPCB) is a type of circuit board that is flexible and consists of multiple layers of flexible substrate material. The basic structure of a multilayer flexible PCB typically includes the following components: Substrate Material: The base material of a flexible PCB is usually made of a flexible polymer, such…
The gold-plated circuit board is divided into electroplated hard gold (gold alloy) and water gold (pure gold) process. The composition of hard gold and soft gold bath is basically the same, but there are some trace elements of metal nickel or cobalt or iron in the hard gold tank. 1. Purpose and effect of gold-plated…
Ultra-thick copper multilayer pcb is an integrated connector with strong and weak electric connection function. The manufacturing technology of ultra-thick copper multilayer pcb sheet over 0.41 mm is studied. The superimposition of single-side copper clad sheet and 1.0 mm black copper sheet and epoxy sheet and single-side copper clad sheet and the bonding of non-flowing…
1. Double sided flexible PCB upper line screen printing First, we need to select materials, baking pretreatment, in order to prevent the contraction of the material deformation to the process after the trouble. 2. The diameter of blanking carbon hole for double sided flexible PCB The blanking carbon hole is generally 0. 8 to 1.…
