These details let us review the PCBA and prepare the assembly process properly.

Question 22

Can you manage several variants of the same board?

Accepted Answer

Yes. We can assemble several variants from the same PCB.

Differences in the BOM, DNP components, part references, quantities or assembly options are included in each version's production instructions.

Question 23

Do you offer fast lead times for electronic prototypes?

Accepted Answer

Yes. EVIACORE offers several lead-time options, including for electronic prototypes and urgent requirements.

Simply tell us your target date so we can propose a lead time suited to your project.

Question 24

How do you inspect electronic boards after assembly?

Accepted Answer

Assembled boards are inspected against the applicable IPC-A-610 Class 2 criteria.

We inspect components, polarities, solder joints and accessible assemblies. Additional checks can be included according to the project's requirements.

Question 25

Which processes do you use for SMT assembly?

Accepted Answer

EVIACORE has production equipment suited to SMT assembly of prototypes and small production runs, including solder paste jetting, automated component placement, vapour-phase reflow and assembly inspection.

This combination gives us considerable flexibility across part references, variants and quantities.

Question 26

How do you deposit solder paste?

Accepted Answer

We use a jetting system to deposit solder paste directly and precisely onto the PCB pads.

This technology is particularly suited to prototypes and small runs because we can adjust paste deposits and volumes to the footprints and needs of each board.

Question 27

Do you use stencils to deposit solder paste?

Accepted Answer

No. EVIACORE does not use stencils for solder paste deposition.

We systematically use our jetting technology to avoid stencil manufacturing costs and reduce assembly costs for our customers, particularly for prototypes and small runs.

Jetting also lets us change paste deposits quickly between PCBA revisions or variants without making new tooling.

Question 28

What are the benefits of solder paste jetting?

Accepted Answer

Jetting precisely controls the amount of solder paste deposited locally on each footprint.

It offers flexibility for prototypes, revision changes and PCBA variants while removing the need for a dedicated stencil.

Question 29

Which reflow process do you use?

Accepted Answer

EVIACORE uses vapour-phase reflow to solder SMT components.

The vapour phase provides even heat transfer around the PCB and components, including assemblies with different thermal masses.

Question 30

Yes. EVIACORE can assemble PCBs without tooling rails, including boards with components very close to the edge.

Our jetting technology and placement equipment allow us to work directly with these PCBs without systematically requiring added rails.

Question 32

How do you ensure the quality of assembled electronic boards?

Accepted Answer

Our approach to quality starts when we prepare the manufacturing file.

Before production begins, we check the assembly data, BOM, references, polarities, PCBs and any special instructions.

We then monitor the assembly stages through to the final PCBA inspection.

Question 33

Which standard do you use to inspect electronic assemblies?

Accepted Answer

We inspect our assemblies against the applicable IPC-A-610 Class 2 criteria.

This international reference defines acceptability criteria for electronic assemblies and helps us apply a consistent inspection method to the PCBAs we produce.

Question 34

How do you handle moisture-sensitive components?

Accepted Answer

We take the MSL rating, packaging and available component history into account.

When needed, components may be baked or prepared appropriately before reflow.

Question 35

Do you visually inspect assembled boards?

Accepted Answer

Yes. We inspect accessible assemblies to check component presence, orientation, placement and solder joint quality, among other things.

The inspection follows the criteria applicable to the project.

Question 36

How do you inspect solder joints beneath a BGA, QFN or LGA?

Accepted Answer

Solder joints beneath these components cannot be inspected directly by ordinary visual inspection.

X-ray inspection is always carried out with our partner when solder joint quality and wetting cannot be verified under a microscope, particularly beneath BGA, QFN and LGA packages.

Question 37

EVIACORE carries out a range of electronic board rework and modifications, including SMT or THT component replacement, solder joint repair, connector replacement, wire modifications, prototype corrections and work on complex component packages.

Question 41

Can you replace a BGA, QFN or LGA?

Accepted Answer

Yes. We perform rework on various electronic packages, including BGA, QFN and LGA.

When connections are beneath the component and cannot be verified under a microscope, X-ray inspection is always carried out with our partner.

Question 42

Can you work on an already assembled electronic board?

Accepted Answer

Yes. We regularly work on assembled boards to make a modification, replace a part or correct a localised defect.

The operation is adapted to the PCB and component to achieve controlled, careful rework.

Question 43

Can you make wire or jumper modifications?

Accepted Answer

Yes. We can add wires or jumpers, cut tracks and make other adaptations on prototypes or batches of boards.

For a repeated modification, we can complete a first board to validate the operation before applying it to the rest of the batch.

Question 44

Can you replace THT through-hole connectors?

Accepted Answer

Yes. We also replace THT through-hole connectors and components.

Our removal and reassembly methods allow us to work on connectors with many pins or substantial thermal mass.

Question 45

How do I request a rework quote?
