Problems solved by technology
However, as SMD products become smaller and smaller (miniature SMD products refer to SMD products with package sizes of 2mm×2.5mm and 3mm×3mm), in the gross leakage test of fluorine oil for sealing, due to the large specific gravity of fluorine oil characteristics, the product is easy to float in fluorine oil, which makes the test control very difficult; and as the market has higher and higher requirements for the quality of SMD products, the gross leak test of its tightness has gradually increased from random inspection to 100% full Therefore, higher requirements are put forward for the device for the gross leak test of fluorine oil. It must be able to accurately and stably carry out the gross leak test on a large number of products at the same time. It is used in the existing basket to solve the coarse leak test of fluorine oil for batches of SMD products. However, the external dimensions of the existing tray are 170mm×170mm, which cannot be directly used for the fluorine oil leak detector with only a 150mm wide inner cavity, and The pallet on the existing production line has a two-layer structure. If it is placed in fluorine oil, the interlayer will seep into the fluorine oil and cause bubbles, which will interfere with product testing.
Therefore, the existing technology cannot meet the process requirements for the gross leakage test of fluorine oil for batch SMD miniaturized products

Embodiment Construction
[0014] See figure 1 , figure 2 , image 3 , the present invention includes a tray 1 and a basket 2, the body of the tray 1 is a single layer, product grooves 1-1 are arrayed on the tray 1, convection holes 1-2 are arrayed on the tray 1, and the convection holes 1-2 are through Hole, through many experiments, we have determined the optimal solution. The tray adopts such a stainless steel single-layer design, which can ensure that it is convenient for testing and not easy to make SMD miniaturized products float out in fluorine oil. At the same time It is conducive to the discharge of fluorine oil. In order to be suitable for SMD miniaturized products, we have designed two types of trays. One tray product has groove parameters of 2.1mm×2.6mm, tolerance -0.04mm, thickness of 2mm, and the number of product grooves is 90. , the groove parameters of another pallet product are 3.25mm×3.25mm, the tolerance is ±0.04mm, the thickness is 2mm, and the number of product grooves is 90; th...

The invention provides a fluorocarbon oil gross leaking test matched device, which can meet the process requirement of the large-batch SMD (surface mounted device) product sealing performance fluorocarbon oil gross leaking test. The fluorocarbon oil gross leaking test matched device comprises a lifting basket and is characterized by also comprising two trays, wherein product grooves are arrayed in the trays, and the two trays are parallelly arranged on the lifting basket.
Description
technical field [0001] The invention relates to a quality inspection device in the production process of SMD (Surface Mount Device) miniaturized products, in particular to an SMD product airtightness detection device, specifically a fluorine oil coarse leakage test matching device. Background technique [0002] At present, the fluorine oil gross leak test of SMD products is such a process: put a small amount of SMD products to be sampled in a simple basket, and then immerse the basket in the 125-degree fluorine oil of the fluorine oil leak detector, and observe whether there is any bubbling Defective products, and then pick out the defective products. However, as SMD products become smaller and smaller (miniature SMD products refer to SMD products with package sizes of 2mm×2.5mm and 3mm×3mm), in the gross leakage test of fluorine oil for sealing, due to the large specific gravity of fluorine oil characteristics, the product is easy to float in fluorine oil, which makes the ...
