Controlling Registration In High Density PCBs, Is a Continues Process. Identifying & Correcting the Specific Causes of Inner-Layer Registration Errors Is also aContinues Process

You will find that over 80% of Inner-Layer Registration Errors occur in the following areas: ARTWORK DEVELOPING PROCESS IMAGING PROCESS LAMINATION PROCESS DRILLING PROCESS

The following images show what kind of data PerfecTest collects and how the data is used to identify various type of Inner-Layer Registration Errors in PCB’s.

All Errors Related to the SIZE OF A LAYER (or the IMAGE) is a Artwork Developing Problem And Are Dealt With By: SCALING or RE-SCALING the ARTWORK

Illustration 1 Illustration 2 Maximum Error Maximum Error -.005” -.005” -.007” -,003” Nominal Location Nominal Location Nominal size .002” Shift from Nominal Actual size Nominal size Actual size A Layer Shift Error ADDED to Expansion ( Layer Size) Error INCREASES the ACTUAL ERROR Total registration error: -.005” + -.005” = -.010” negative expansion error only corrected with scaling Total registration error: -.007” + -.003” = -.010” combination of shrinkage & shift error corrected with scaling & process adjustments

Layer Rotation Layer Shift Layers 2 and 3 shifted from one and other Layer 3 nominal but layer 2 has rotated clock vise. Front to Back Registration Error Occur during the Imaging Process Layer 2 (Red) Layer 3 (Green)

Core Rotation Core Shift Core for layers 2 and 3 rotated clock vise from Core for layers 4 and 5 Core for layers 2 and 3 shifted from Core for layers 4 and 5 Core to Core Registration Error Layer 2 (Red) Layer 3 (Green) Layer 4 (Yellow) Layer 5 (Purple) Occur during the Lamination Process

All layers of panels are shown in Red and Green Yellow outline indicate correct, or nominal position of panels Panel 2 Panel 3 Panel 1 Panel to Panel Shift Registration Error Occur during the Drilling Process

PerfecTest keeps records of Panel Construction Variables The importance of this is to learn the behavior of all Panel Construction Materials

Corrected Scaling Factors PerfecTest Calculates Corrected Scale Factors When Each Test Session Is Finished

With PerfecTest you can SEARCH for Best Matching Scale Factor for new jobs from jobs already in the PerfecTest database

Registration Errors Are Always a Combination Of Different Causes Registration Errors Shift Errors Expansion Errors Scaling Artwork Repetitive Shift Error Random Shift Error Imaging Imaging Lamination Lamination Drilling Drilling

The PerfecTest can be NETWORKED within your factory, to allow each engineer to view the PerfecTest data, that applies to the engineers factory responsibility, so the engineer can repair the process, to avoid further inner-layer registration errors
