What Should Customers Note When Purchasing Components?

In SMT patch manufacturing, several customers will get their parts to locate SMT manufacturers for set processing, so what problems should be taken note of when buying elements? Noting: Each plan should include the very same component number, package, and value info as in the BOM. If possible, it is best to place a code word on each bundle. If there is any difference from the details in the BOM, you need to call us ahead of time to correct the BOM.

Components Excess: Resistors, Capacitors, and diodes (0603, 0805, 1206, 2225, SOT, TURF, MELF – plans) need a minimum of 50 pieces and need to go beyond the asked for quantity by 30 items. (Example: Assembly Amount 40 pieces – we will need 70 items – this satisfies our minimum of 50 pieces plus the Setting up Quantity 30 pieces). Resistors, Capacitors, and diodes (0201, 0402, Mini Melf, Micro plans) require a minimum of 100 pieces and must surpass the asked for amount by 50 pieces. (Example: Setting up Amount 80 items – we require 130 items – this fulfills our minimum of 100 pieces plus the 50 items unwanted of the Assembly Quantity). Small unwanted (1-5 pieces based upon the overall Setting up Amount) is required for pricey components such as IC, BGA, QFP, Connectors, etc, which will certainly make sure smooth SMT assembly and on-time distribution of your constructed boards.

Packaging: SMT components that are not provided in reel kind ought to be positioned on a continuous strip of tape. If you require to construct the exact same SMT parts on different boards, do not reduce them into strips, put them on a constant tape or reel. Elements on tubes or trays are likewise appropriate for setting up.
