J-STD-001 PRACTICE EXAMINATION 2026 QUESTIONS
WITH ANSWERS GRADED A+
● The materials and processes used to assemble/manufacture electronic assemblies
SHALL be selected such that their use, in combination, produce products acceptable to
this standard.. Answer: [D1D2D3]
● When major elements of the proven processes are changed, e.g., flux, solder paste,
cleaning media or system, solder alloy or soldering system, validation of the
acceptability of the change(s) SHALL be performed and documented, see Appendix B
J-STD-001 Guidance on Objective Evidence of Material Compatibility.. Answer:
[N1N2D3]
● Manufacturers, when specified, SHALL have a Pb-free control plan (LFCP), which
should be established between the Manufacturer and the User.. Answer: [D1D2D3]
● The electrical and mechanical integrity of components and assemblies SHALL be
retained after exposure to processes employed during manufacture and assembly, e.g.,
handling, braking, fluxing, soldering and cleaning.. Answer: [D1D2D3]
● There SHALL be a documented process to control materials, including consumable
materials that are subject to age degradation.. Answer: [N1D2D3]
● Limited shelf life items SHALL be stored and controlled in accordance with the
materials manufacturer's recommendations or in accordance with the Manufacturer's
documented procedures for controlling shelf life and shelf life extensions.. Answer:
[N1D2D3]
● Unless otherwise specified on the engineering documentation, materials SHALL be
processed (mixing, curing, etc.) per the material specification or other documented
procedure.. Answer: [N1D2D3]
● Material SHALL be used within the pot life (working time) specified by the material
manufacturer or used within the time period indicated by a documented system..
Answer: [N1D2D3]
● When curing conditions (temperature, time, infrared (IR) intensity, etc.) vary from the
material manufacturer's recommended instructions, they SHALL be documented and
, available for review.. Answer: [N1D2D3]
● Items exposed to uncured silicone material SHALL NOT be used for processing other
material.. Answer: [D1D2D3]
● An authorized exception is allowed only in cases where equipment is used for
co-curing processes and the Manufacturer has demonstrated through system tests
that non-silicone material properties have not changed and design requirements are
met. Objective evidence SHALL be maintained and available for review.. Answer:
[N1N2D3]
● Solder alloys SHALL be in accordance with J-STD-006 or equivalent.. Answer:
[D1D2D3]
● Solder paste SHALL be in accordance with J-STD-005 or equivalent.. Answer:
[D1D2D3]
● Flux that is part of flux-cored solder wire or preforms SHALL meet the requirements
of 3.3 Flux.. Answer: [D1D2D3]
● Pb-free processing SHALL be in accordance with a documented procedure that
includes adequate controls to minimize the risk of cross-contamination with Pb..
Answer: [N1D2D3]
● Solder used for preconditioning, gold removal, tinning of parts and machine
soldering SHALL be analyzed, replace or replenished at a frequency to ensure
compliance with the limits specified in Table 3-1.. Answer: [N1D2D3]
● SnPb solder alloys other than Sn60Pb40, Sn62Pb36Ag2 or Sn63Pb37 SHALL be in
compliance with equivalent documented limits.. Answer: [N1D2D3]
● If contamination exceeds the limits, intervals between the analyses, replacement, or
replenishment SHALL be shortened.. Answer: [N1D2D3]
● Records containing the results of all analyses and solder bath usage, e.g., total time
in use, amount of replenishment solder or area throughput SHALL be maintained for a
minimum of one year for each process/system.. Answer: [N1D2D3]
● SnPb alloys used for preconditioning or assembly SHALL have a tin content
maintained withing +/- 1.5% of the nominal alloy, e.g., 63 +/- 1.5% (i.e., 61.5% - 64.5%,
being used.. Answer: [N1D2D3]
