A planned route for leaded components
Provide hole and lead data, insertion details and component thermal limits. Review wave, selective or manual soldering with the SMT sequence, mechanical support and inspection criteria for your board.
Review component insertion alongside wave, selective and manual soldering. Each method needs a review of access, support and thermal requirements rather than a blanket assumption about suitability.

| Layout or component concern | Clarification required | Method and output to review |
|---|---|---|
| Crowded solder side | SMT exposure, nozzle access and masking drawing | Assess wave / selective suitability and the protection / support plan. |
| Thermal-sensitive connector | Manufacturer limits, seating height and allowed exposure | Assess selective / manual operation; agree first-unit seating and joint checks. |
| Heavy ground plane | Hole / lead dimensions, thermal mass and access | Review soldering approach and tooling; define the joint acceptance evidence. |
Through-hole components remain relevant where the design needs leaded connectors, larger devices or mechanical support through the board. KeepBest reviews THT and mixed technology assemblies using the component drawings, hole data and soldering requirements. The right route may involve wave, selective or manual soldering, depending on board access, thermal limits and the agreed build scope.
Compare finished hole dimensions, lead geometry and component tolerances before insertion. Connector height, polarity, lead forming and board seating matter to both electrical assembly and the mechanical fit of the finished product.
Access, thermal limits, masking and quantity determine the suitable operation.
Review the solder side, exposed SMT parts, masks and support needs before selecting a wave route. Identify components or areas that must be protected, and agree the intended soldering and inspection conditions.
Assess nozzle access, nearby components and the board's thermal mass for local soldering. Keepouts and processing requirements depend on the actual layout and tooling; generic clearance values should not replace project review.
Some devices, wires or low-quantity assemblies need manual operations. Define the soldering instructions, lead preparation, strain relief and inspection criteria, particularly where thermal exposure or access makes automation unsuitable.
Resolve support, connector and access constraints before another operation closes them off.
Plan through-hole insertion and soldering alongside SMT placement and reflow. A clear sequence avoids leaving sensitive parts, restricted access or mechanical interference to be discovered after another operation has already been completed.
Inputs, decisions & outputs
Check the fabrication and component drawings together to understand lead fit and seating. Resolve polarity, connector height and lead-forming instructions before materials and the insertion route are prepared.
Review wave, selective or manual options against board access, component restrictions and quantity. Confirm the proposed route and required supports or masks as part of the manufacturing scope.
Use the approved assembly drawing and process instructions for the intended component positions. Special manual tasks, wire attachments and protected areas follow the agreed requirements for the released design.
Review insertion, polarity, component seating and solder workmanship under the agreed criteria. Electrical or functional checks follow separately where specified, with any rework or nonconformance handled through the approved disposition process.

Before release
Leaded connectors, larger components and mechanically loaded parts can make THT relevant. The design must still address hole fit, retention and electrical requirements; through-hole mounting alone does not prove the reliability of a product.
No. The layout, component temperature limits, solder-side access and quantity influence the route. Selective or manual soldering may be more suitable for particular areas or devices, subject to engineering review.
Provide the complete populated-side information and THT instructions. Engineering needs to assess access, protection and thermal sequence for the mixed assembly before confirming the process and inspection plan.
No fixed clearance is presented as a capability here. Nozzle access, neighboring parts, supports and thermal demands vary by design. Review the actual drawings and proposed tooling with engineering.
Component sourcing can be requested in the reviewed order scope. Provide manufacturer part numbers and mark consigned parts, approved alternatives and any supplier requirements so purchasing and incoming inspection responsibilities are explicit.
