To clean or not clean before PCB Assembly? ept.ca/news/to-clean-…
ARM explains good interrupt control for low power processors ow.ly/2sBg7F
Below a few millivolts, thermal electromotivie forces (EMFS) can really have an impact on low-level analog signal integrity.
#PCBDesign Isolate critical portions of the circuit design to reduce EMI
Three sets of PCB Adhesives - Permanently bonded laminates, pressure-sensitive adhesives bond stiffeners and conductive adhesives.
Proper use of stiffeners will aid areas where components are placed!
#PCBDesign all electrical signals have a signal conductor and signal return path...
PCB Design Considerations ... Rise/Fall Time, Skew, Jitter, Intermodulation distortion, phase distortion, crossocver distortion...#PCB
The preferred insulation material for a flex circuit is a coverlay! So choose wisely!
IR/CO2 Laser Drilling require Thermal Ablation, larger focus diameter, larger beam size, percussion drilling, high dielectrical removal, etc
Conductor Materials use electrodeposited copper, rolled annealed and high tensile elongation(HTE) copper! Dynamic Applications = HTE
In choosing conductor materials make sure you have the right copper type and thickness. Common thicknesses are 12um, 18um and 35um!
When choosing a conductor material look at the materials performance during YOUR specific application!!
Requirements of a Flex Material: Electrical Properties, Thermal Resistance, Tear Resistance, Low Moisture Absorption and chemical Resistance
Requirements of a Flex Material: Bending, Flexibility, Dimensional stability, components, circuit density, impedance characteristics & more!
What materials have you used in your Flex Circuits construction?
Who requires PCB Layout? We're thinking about providing a in-house service for all our customers. Just provide us with your Schematics & BOM
