    • A tray for handling and retaining a plurality of small components comprising a rigid body portion with a plurality of pockets formed therein. Each of the pockets has an elastomeric contact surface for contacting and retaining a component. The contact surface may be formed from a thermoplastic material having a surface energy between 20 dyne/cm and 100 dyne/cm, and a surface electrical resistivity of between about 1×104 ohms/square and 1×1012 ohms/square. The material for the contact portion may be urethane, polybutylene terephthalate, polyolefin, polyethylene terephthalate, styrenic block co-polymer, styrene-butadiene rubber, polyether block polyamide, or polypropylene/crosslinked EDPM rubber. The body portion may be formed from acrylonitrile-butadiene-styrene, polycarbonate, urethane, polyphenylene sulfide, polystyrene, polymethyl methacrylate, polyetherketone, polyetheretherketone, polyetherketoneketone, polyether imide, polysulfone, styrene acrylonitrile, polyethylene, polypropylene, fluoropolymer, polyolefin, or nylon. The body portion may have a peripheral border region and a downwardly projecting skirt portion to facilitate stacking of multiple trays.
    • 一种用于处理和保持多个小部件的托盘,包括刚体部分,其中形成有多个凹穴。 每个口袋具有用于接触和保持部件的弹性体接触表面。 接触表面可以由表面能在20达因/厘米至100达因/厘米之间的表面电阻率和大约1×10 4欧姆/平方英寸的表面电阻率的热塑性材料形成, 12欧姆/平方英尺 用于接触部分的材料可以是聚氨酯,聚对苯二甲酸丁二醇酯,聚烯烃,聚对苯二甲酸乙二醇酯,苯乙烯嵌段共聚物,苯乙烯 - 丁二烯橡胶,聚醚嵌段聚酰胺或聚丙烯/交联的EDPM橡胶。 主体部分可以由丙烯腈 - 丁二烯 - 苯乙烯,聚碳酸酯,聚氨酯,聚苯硫醚,聚苯乙烯,聚甲基丙烯酸甲酯,聚醚酮,聚醚醚酮,聚醚酮酮,聚醚酰亚胺,聚砜,苯乙烯丙烯腈,聚乙烯,聚丙烯,含氟聚合物,聚烯烃或尼龙形成。 主体部分可以具有周边边界区域和向下突出的裙部部分,以便于堆叠多个托盘。
