PRODUCT PARAMETERS Unit (mm)

PRODUCT ADVANTAGES:

① Improve the accuracy of back drilling position and reduce drill needle wear.

② The margin design (metal edge) greatly facilitates the operation of the mushroom head of the drilling rig during back drilling and improves production efficiency.

③ It has recycling value, which can effectively save costs and meet environmental protection requirements.

METHOD OF USE & STORAGE CONDITIONS:

① When used, the special material is facing up (the resin surface is the first contact surface material in the drilling process), the aluminum sheet is facing down and covered on the PCB of same size, and the four sides are fixed with textured adhesive paper or mechanical means, and there is no arching visually. 

② The drill needs to reserve a chip removal space of 10% to 20% of the effective edge length. 

③ Placed horizontally, the original packaging storage period is six months, temperature control <35℃, humidity control <RH70%.
