There are one value for thickness during PCB-teach function which is the PCB thickness. The other one is the camera focus in machine option but it is a dangerous function because the camera focus is adjusted by raising/lowering table.

PCB Thickness and BLR

Electronics Forum | Mon Jun 03 13:26:32 EDT 2019 | az2019

Hi, I have a general question about the relationship of PCB thickness and BLR testing result. For example, I have QFN6x6 parts mounted on board in 1.2mm, 1.6mm, and 2.4mm thickness. All boards have 6 layers of Cu. Studies show thicker board gives les

Typically, the reliability of PCBs suffers significantly due to the increase in aspect ratio. It is not preferred to opt for high thickness boards. However, I would like to point out that your assumption seems to be wrong as board layers do not direc

This should be possible, but definitely get the OK from your customer first! Layer thickness may effect things like impedance, EMC, or other electrical properties of the assembly. out of curiosity, why do you want thicker boards?

Hi I addition to the mentioned electrical effects, there are also reliabilty issues with increasing the board thickness, such as increased aspect ratio for the vias or registration difficulty

PCB Plating Thickness Meter???

Electronics Forum | Tue Aug 30 22:38:54 EDT 2005 | cabs

Does any one knows where to get a plating thickness meter that can be use in the fine pitch contacts and trace in PCB application like BGA pads? If there's a hand held device at lower cost much better... Also if you can recommend companies that offer

Is IPC-9701 apply to QFN package?

Electronics Forum | Sun May 24 21:12:59 EDT 2009 | keith78

I have a problem recently to qualify QFN package on solder joint reliability. The pcb thickness stated in IPC-9701 is 2.35mm but from the in-house test, QFN surface mount on 2.35mm thickness PCB board have a short cycle to failure due to higher CTE m
