PCB是什么?
PCB看上去像多层蛋糕或者千层面--制作中将不同的材料的层，通过热量和粘合剂压制到一起。从中间层开始吧。 FR4 PCB的基材一般都是玻璃纤维。大多数情况下，PCB的玻璃纤维基材一般就指“FR4”这种材料。“FR4”这种固体材料给予了PCB硬度和厚度。The board lamination process is a culmination of the work performed on the individual layers, and the process can be divided into two complementary jobs: Layup A physical representation of the board stackup designed at the outset of the layout.

A Pioneering Tactic for Sustainable Waste Management:
Design of a Cost-Effective Recycling Machine A. Agarwal1* 1Department of Mechanical Engineering, University of Botswana, Gaborone.Botswana Abstract.In this paper we discussed the new design, fabrication and testing of a mechanical can crusher taking into deliberation the force analysis and ergonomic factors that will enable people toSamples of PCB were obtained from discarded computer, and major electronic components including capacitors, resistors, and batteries were manually removed before crushing. The samples were crushed into less than 0.3 mm using a cutting mill (SCP-180-2, Cixi Yinbao Plastics Machinery Co., Ltd.), and particles of 0.2–0.3 mm were used for flotation.Copper recovery from waste printed circuit boards by the

The PCB Recycling Process in Design and Electronics Production
PCB recycling begins with the physical process of drilling/sorting the boards to remove components, and then cutting the boards into smaller chunks. This process removes capacitors, motors, batteries, plugs, semiconductors,,fasteners, and other parts from a PCB. Additionally, magnetic separators pull ferromagnetic materials away Hx Mini Small Shaft Home Household Pet Pp Pcb Drum Film Bottle Jumbo Bag Crushing Shredding Machine And Crusher Plastic Shredder, Hx Mini Small Shaft Home Household Pet Pp Pcb Drum Film Bottle Jumbo Bag Crushing Shredding Machine And Crusher Plastic Shredder,Plastic Shredder,Plastic Shredder Hx Mini Small Shaft Home Household Pet Pp Pcb Drum Film
