Partnership and after-sales service — we are with you after shipment
Working with Siltegro does not end with the shipment of the finished product. We diagnose and correct defectively designed electronics, repair customers' damaged electronics and carry out professional rework and service. One partner through the entire product lifecycle.

Diagnosis and repair of faulty electronics
If a device was defectively designed or faulty units reached the client — we analyze the cause, identify the problem and propose a solution. Diagnosis covers schematic analysis, AOI and X-Ray inspection and functional tests.
PCB rework
Repair and replacement of components on an assembled board — from single corrections to implementing design changes across a whole batch. Detailed description of methods and the IPC 7711/7721 standard can be found on the PCB rework page →
Repair of damaged electronics
Repairs of customers' damaged electronic devices — both produced by Siltegro and external ones. Electrical diagnostics, replacement of damaged components, verification after repair.
Support with design modifications
If the product requires a change — a component, circuit or firmware — we carry out the modification and validate the result. Cooperation with the engineering department on ECO (Engineering Change Order) design.
Long-term partnership
We treat every client as a business partner — not a one-off order. Ongoing updates at project stages, proactive communication about potential issues and support at every stage of the product lifecycle.
Who is after-sales service for?
Companies that received a faulty batch
If defects were found in the delivered volume — we diagnose the cause and carry out repair or replacement. Fast response, full documentation.
Companies with a design requiring modification
Does the product work but require a component change or circuit correction? We implement ECOs without engaging a new supplier.
Companies needing BGA rework
BGA replacement requires specialist equipment and experience. We carry out BGA rework as per the IPC 7711/7721 standard.
Clients looking for a long-term EMS partner
Not just a manufacturer — a partner who understands your product and supports its development at every stage.
IPC 7711/7721 — the standard for rework and repair
IPC 7711/7721 is the international standard for the repair and rework of electronic assemblies — a complement to IPC-A-610 for rework and modification processes. Siltegro carries out service and rework per this standard, which means documented procedures, certified methods and traceability of every repair.
What sets us apart in after-sales service?
Full knowledge of the product
We service primarily the devices we produced ourselves. We know the documentation, batch history and project specifics — no need for a new onboarding.
X-Ray in diagnostics
The new X-Ray machine lets us diagnose defects hidden under BGA and QFN components — causes of failures invisible to the naked eye.
IPC 7711/7721 as the standard
Rework and repairs carried out as per the certified standard — not "by eye". Documentation of every repair stored for up to 10 years.
Partnership, not a transaction
We inform about potential problems before they become failures. Regular contact, proactive communication, one caretaker through the whole product lifecycle.
