PC board of internal stress in the process of extrusion and cooling to finalize the design, and the appearance of the PC board basically didn't attack the placement of any changes may use in the process, will experience a stress lax effect, some eliminate to some internal stress. But only limited experience lax PC board is very difficult to eliminate the stress, stress, which have assumed in use do not pay attention to during the process of increasing external stress, surface will attack and close to the appearance of some deformation and from then on is now easy to break point (fine crack, crack). Therefore, we in the use of it is necessary to prevent the incorrect perhaps far external stress

Led to many PC plank crack elements, the main sheet and the methods, materials, construction and other aspects of the contact is larger. Assume that plan is not reasonable, select material is not correct, may be in the process of construction was not well done some very details, will cause the PC board crack.

Assume that humid environment of the PC board placed far maybe monotonous will have owe good, too wet will attack swell, too monotonous and can shorten, so the brief that PC plate cracking, about these questions, let's processing method are:
