PASS
Integral part of the manufacturing and testing process; considered in all aspects during the
manufaturing process and NOT confined to an evaluation at the end of the line
SPC (Statistical Process Control)
What is an example of an SPC?
In-process coupon evaluation may be cross-sectioned and evaluated; first article inspection may
be performed to ensure the remainder of the lot would be in conformance
These specimens are representative of a the product produced and must represent the process
Test coupons / specimens
What is the purpose of in-process test coupons?
Provides a systematic path for continuous improvement, identifies root causes of problems,
reduces the number of evaluations that need to be made at the end of the production cycle
Hole solderability, thermal stress, plating thickness, layer registration, anything related to hole
condition within a 2-sided/multilayer board
Test coupon AB/R evaluation
Ability of a product to function under given conditions and for a specified period of time
without exceeding acceptable failure limits
Reliability
What is the importance of reliability?
Determine the functionality of equipment and the environment in which it is to operate
1|Page
,Stress testing to failure, focuses on reliability
HAST
Eliminate infant mortality
Burn-in
Identifies mechanical, physical, visual and electrical test normally required by a customer in
order to ensure that the quality life-cycle tracking data is available; specified on applicable
performance specification
Product Quality Life-Cycle Tracking
Frequency of examination; identify if a production lot meets specific requirements
Sampling plan
What does IPC recommend in term of sampling plans
Zero-base (no defects in the sampled lot)
No defects in the sample lots; if defects are found, the entire lot must be examined
zero-base
What should every manufacturer have as an important measurement tool that is simple and
easy for the operators to enter data?
Quality documentation plan
Easy method in the form of labels for operators to record documentation
Bar codes
Regulations focused on materials or substances that are contained in products
ROHS and REACH
3 nodes of solder joint failure
Fatigue caused by thermal cycles, sudden shock (drop) or stress, long-term stress
Most common form of solder joint failure
Fatigue caused by thermal cycles
What is the best part for risk to solder cracking due to thermal mismatch?
Leadless components and castellation-type leads
2|Page
, What are key cost drivers for bare board manufacturing?
Laminate materials/mixed dielectrics, number of layers, total number of holes, minimum hole
size, panel utilization, lamination cycles, co-planar, plated via-in-pad epoxy filled, back-drilling,
impedance control
DRC's for fabricators and assemblers often do not take into account what type of DRCs
electrical DRC's such as controlled signal lengths for timing
Rectangular sheet of base material that is used for the processing of 1+ printed boards, and
when required, one or more test coupons
Fabrication Panel
Printed board image/patterns plus the additional contiguous deliverable material from the
panel (+ tabs, fiducials, tooling holes, etc...)
Assembly Array
What is the most common size panel?
18x24in, 460x610mm
Stencil manufacturer work to what location/
Nominal positioning location between two-dimensional variations
What should the designer consider adding to help the stencil manufacturers?
Alignment fiducials
What ratio should you never go beyond in terms of the length-to-width ratio?
12:!
How do long, thin boards jeopardize conductor routability?
Routing is primarily on the longitudinal axis and may cause crosstalk and signal integrity
problems
What is the benefit of copper balancing?
Uniform exposure to the etching solutions
Addition areas of copper foil intended to draw copper in the plating bath away from the fine
conductor images; uniform plating distribution
Plating Thief
