Films: life afloat
As always, the 2017 edition of the PĂȘcheurs du Monde film festival in Lorient, France, showcased examples of the courage, resistance and resilience of fishing communities
France: A richness of exchanges
For the 21st year running, the Collectif PĂȘche & DĂ©veloppement celebrated world Fisheries Day (November 21, 1997) at a symposium organized with UBS university and student participants on the theme âRecognizing fishersâ knowledgeâ. There is a trend towards the marginalization of fishermen, as highlighted in a statement to the European Commissioner for the Oceans: âFisheries... is absent from the European Commissionâs strategy to ensure the growth of the blue economyâ... and âsustainable fisheries and fishing communities are likely to be the losers.â A student from Djibouti named Djoumah Ali observed: âIt is not a question of denouncing all the measures or activities related to the blue economy but of taking into account the fishermenâs opinions. This is not really the case today at the international level in the debates on the future of the oceans.
RF Shield Pick Bridge
RF shields are used to contain the radio waves. The shields prevent waves from escaping the source and prevents the source from interacting or disrupting other frequencies in the proximity. A pick structure is generally designed within the perimeter in the static or fixed part of the RF shield with consideration of electronic components on the PCB, thermal heat spreader, mechanical fasteners, etc.
The purpose of the pick structure is to provide and support a pick region during SMT operation. The RF shield fences are picked from the center of gravity of the fence, using the frame of the fence pick structure with the help of a suction nozzle assembly in the SMT operation. This automated operation also places the shield fence on the circuit board for assembly. After placement and the reflow solder process, the pick structure is manually or automatically removed to allow for subsequent operations such as automatic optical inspection of electronic components, edge bonding, rework of components, and assembly with a hard removable shield lid or a foil lid through mechanical and chemical adhesion to become one whole RF shield
