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

I would like to enter the discussion by tossing some numbers in. First of all I don�t like the 3 Sigma value. 3 Sigma are 2000 defects per mio. if I remember correctly. This means, if you have 200 components on the board, then every 10 boards have on

JD: It's important to note that FR-4 does not contain PBB or PBDE. The bromine in FR-4 epoxy comes in the form of tetra-bromo-bisphenol A [TBBA], which polymerizes and become part of the cross-linked epoxy. Bromine, in the form of hydrogen bromide, i

Juki machines generally are great machines for reliablity and maintaining overall accuracy as they have full linear (mag-scales) encoders on XY axis and self calibration features. Laser centering has its pros and cons - mostly pros, but can have iss
