protel99se常用元器件封装(国外英文资料)
Parts packaging refers to the indicator of the actual parts is welded to the circuit board and the appearance of the position of the solder joints. Is the pure concept of space. So different elements can share the same parts package, the same element can also have different packaging parts. As a traditional needle type resistance, the element size is large, the circuit board must be drilled to accommodate components, upon completion of the drilling, insert, and tin or tin spraying (or hand welding), high cost, newer designs are used in surface mount small volume type element (SMD) of the element without drilling, steel film semi fused solder paste into the circuit board, and then put on the SMD element, can be welded on the circuit board.
