What Should Customers Pay Attention to When Purchasing Components in SMT Production?

In SMT spot production, many customers will buy their parts to find SMT manufacturers for set processing, so what troubles should be paid attention to when buying elements? Noting: Each bundle must include the exact same component number, bundle, and worth information as in the BOM. Preferably, it is best to place a code word on each package. If there is any kind of distinction from the details in the BOM, you ought to call us beforehand to deal with the BOM.

Components Excess: Resistors, Capacitors, and diodes (0603, 0805, 1206, 2225, SOT, TURF, MELF – plans) need a minimum of 50 pieces and have to surpass the asked for amount by 30 pieces. (Instance: Assembly Amount 40 pieces – we will certainly require 70 items – this fulfills our minimum of 50 items plus the Setting up Amount 30 items). Resistors, Capacitors, and diodes (0201, 0402, Mini Melf, Micro packages) call for a minimum of 100 pieces and have to exceed the requested amount by 50 pieces. (Instance: Assembly Quantity 80 items – we require 130 items – this meets our minimum of 100 pieces plus the 50 pieces extra of the Setting up Quantity). Tiny excess (1-5 pieces based on the complete Assembly Quantity) is required for pricey parts such as IC, BGA, QFP, Connectors, etc, which will make certain smooth SMT assembly and on-time shipment of your put together boards.

Product packaging: SMT components that are not supplied in reel form must be positioned on a continuous strip of tape. If you need to assemble the very same SMT parts on various boards, do not reduce them into strips, place them on a constant tape or reel. Components on tubes or trays are also ideal for assembly.
