A brief Discussion on how much solder paste is needed for printing PCB boards?

PrintingPCBHow much solder paste is needed for the board? This is each one.SMTA problem that all engineers should consider. So how can the amount of solder paste be estimated more accurately? The following solder paste manufacturer will explain it to you:

First of all, it is necessary to understand clearly what kind of statistics such a amount of solder paste is mainly used for. If it is used to estimate a certain typePCBWhen it comes to the amount of board used, people generally choose the following specific methods:

1Weigh first10The weight of the sheet light plate is measured after printing10Calculate the weight of each board.

2Please ask the steel plate supplier to supply the area of the openings for each steel plate.

3By the area of the opening*Steel plate thickness, determine the volume;

4By weight/Volume acquisition density

5After that, whenever this type of solder paste is needed, the amount of solder paste for each board can be directly analyzed=The area of the opening*Steel plate thickness*Solder paste density*(1+0.2";" Among them0.2For consumption. In this way, add the amount of solder pasteBOMIn the process, the material control calculates the usage amount of solder paste based on the requirements of business orders.

If it is expected to be used as the amount of solder paste for each type, it is indeed too precise and cannot be common. They also carried out the analysis, all following the specific methods as follows: collecting the points for half a year, the points of the solder paste processing technology, and then analyzing the usage of solder paste within half a year, and finally dividing by the actual solder paste.

Advantages: The amount of solder paste consumed during the operation process is also included in the scope of single solder paste, making it more reasonable and effective to calculate the production cost. The operation process of cleaning and scrapping will consume a large amount of solder paste.

Disadvantage: It's not easy to talk to these meticulous buyers. This is because compared with various types of products, some have suffered losses while others have found good deals.

Strictly speaking,Solder pasteFor the quantity issue, single-board testing should be carried out, and a certain amount of solder paste should be determined for each product.
