4.Let me tell you some acknowledge about PCB.
1) Confirm the way of PCB impedance gauge point?The process, must pay attention to what control point on the PCB impedance value will fall on the optimal point?

PCB impedance impact factor has four most, is the dielectric thickness and dielectric coefficient, line width, line thickness.Direct measurement of the actual impedance value does not generally circuit board, as adopted by the time-domain reflectometer tester (TDR), it has some match the impedance measurement conditions, not all lines can be directly measured.So companies most design standard sample at the edge of the product or production edge, impedance condition to the simulation of actual products.Process control, as long as related to the impedance parameters should be included in the control, such as: material type, thickness uniformity, line width, the thickness of copper should consider.

To achieve optimal value and there is no simple answer, each manufacturer should be based on their use of all materials and process parameter adjustment, experts can't answer, unless he can directly involved in the whole process and full control of all factors.In addition it is worth mentioning that the test sample should be revised in accordance with the actual performance, at the same time should be confirmed with the product real electrical performance to maintain constant relationship, or just the pursuit of sample impedance accurately, there is no way to really improve product electrical performance directly.

2) What is the leakage coefficient? Ion drift in the PCB what is the effect?

Problem is a little fuzzy, I believe you should be referring to the reliability test of an argument that is able to live under a certain voltage per unit thickness time and conditions, this kind of appellation are commonly called "dielectric strength" or "insulation resistance", its standard varies with the product and material.For example: some communication product will ask under 500 v or higher voltage, won't produce leakage phenomenon.And some special product, can ask in the atmospheric pressure, saturated humidity, continuous testing under 85 ℃, 85 hours, does not produce short circuit phenomenon. But these two requirements of physical meaning is not the same, the former phenomenon should be your so-called leakage coefficient, while the latter is a kind of reliability test, and is different from what you said the leakage coefficient, but when electrical fault happened, are somewhat similar phenomena.

Insulation condition will change with its containing moisture level, and can control the level of saturation can only use a certain environment humidity to set, so the test error changes actually there must be, must pay attention to it.You should said Ion drift is Ion Migration, it is because of the voltage difference between the two conductors, when the presence of ionic Ion movement will be driven by electric field.After a period of time, when the motion path created a ion channel make insulation voltage is reduced, at this time there will be a risk of short circuit, thus make electronic products reliability crisis.For your reference
