FPC assembly Pallets features

I would like to introduce the comparison between Magnetic reflow pallets and silica gel plate.

A. Stability: magnetic reflow pallet in magnetic state to even out the FPC, as the physical process,magnetic may increase or decrease according to request, don't change due to factors such astemperature, time, relatively stable.Silica gel plate adopt chemistry, will change under differenttemperature or Time or other condition, which lack of stability. Especially in the use of a certainperiod of time after a drop in viscosity, and not clean viscosity decreased during us, which cause FPC substrate deformation while crossing the reflow soldering and affect the welding quality.

B. Usage Life: magnetic reflow tray used in magnetic material and working principle of physicalprocess, are high temperature resistant material,As long as it's not  destroyed by man or at accident situation, it can be permanent online.  statecan use permanent damage and accidents.Silica gel plate in use process, USES the chemical process,Inuse process, it will be aging of due to silicone materials, including Japan's material, no more than1000 times return.The cost is very high.

C. Quality: magnetic reflow pallet at work on FPC insulating protection at the same time, FPC won’t be destroyed when workman pick up the FPC.Silica gel plate in use process to ensure the smooth ofFPC, has certain viscosity,and will stick to FPC, which will be difficulty for picking up FPC andmay cause FPC deformation.

Comparison between Magnetic reflow pallets and normal plateA.Quality: magnetic reflow pallet, because of FPC flat surface cause from the steel, reflowsoldering will be reduced during FPC flow, which can guarantee the stability of welding quality,reduce adverse.Ordinary tray can only be used with high temperature tape around the FPC, afterreflow soldering, which easy to cause deformation to the middle part of FPC, tin water to overflow, cause badwelding, which will affect the quality. At the same time, magneticReflow soldering tray can reduce some difficulty, like can avoid the high temperature stick to Flexible pcblead to hard FPC being picked up or flexible PCB deformation.

Cost: magnetic reflow soldering tray, convenient to use,  reduce prework workers, and the personto take off the tape after reflow soldering, at meanwhile, can reduce the use amount of the hightemperature tape. Investment is bigger at first time to magnetic reflow soldering tray, however, ithas cost advantage for mass production.
