What is the difference between these two types? The editor will explain it to you.u003c/pu003eu003cpu003eu003c/pu003eu003cpu003eThe first type: voltage processu003c/pu003eu003cpu003eu003c/pu003eu003cpu003eUsing high temperature to press the non-woven fabric A non-woven bag combined together. The current widespread method is to use ultrasonic pressure welding, which is a primary internal interconnection method used to connect to the actual die surface or the primary internal interconnection method of the device logic circuit. This connection method combines logic signals or The electrical signal of the chip is connected to the outside world. Other primary interconnection methods include flip chip and tape-and-reel automatic welding, but ultrasonic pressure welding has an advantage in these connection methods, and more than 90% of all interconnection methods use this method. u003c/pu003eu003cpu003eu003c/pu003eu003cpu003eSecond: Sewing processu003c/pu003eu003cpu003eu003c/pu003eu003cpu003eA sewing method in tailoring. It is mainly used by sewing machine to stitch and wrap fabric, leather and other products to form a bags, which is an important link in knitted products. Since different fabric strips are stitched together, and also stitched from different angles and different methods, usually a complete sewn bag may take 5 or 6 steps to make a sewn bag.u003c/pu003e u003cpu003eu003c/pu003eu003cpu003eComparing these two processes, the sewing process is more complicated than the voltage process, so its price may be slightly more expensive than the voltage non-woven bag. And it is precisely because it is manually stitched manually, so the sewn non-woven bags bears more weight than the voltage non-woven bag, and it can bear it without breaking. u003c/pu003eu003cpu003eu003c/pu003eu003cpu003eThe above are the two processes of non woven bags explained by the editor of the non-woven bag manufacturer.
