A resistance-to-soldering-heat report answers a separate question: whether the component tolerates the defined assembly heat exposure. Buyers should request both when their application requires both, then match the sample, terminal option, process conditions and acceptance criteria to the ordered switch. A generic statement that a switch is \u201csolderable\u201d is insufficient to approve a production process.<\/p>\n<p>This guide explains how to review supplier evidence for industrial control-panel buttons. It does not prescribe a universal iron temperature, dwell time or rework allowance. Those settings require the exact manufacturer&#8217;s instructions and a validated assembly process.<\/p>\n<h2 id=\"section-1\">What the two tests actually establish<\/h2>\n<p>The <a href=\"https:\/\/webstore.iec.ch\/en\/publication\/61104\" rel=\"noopener\" target=\"_blank\">IEC 60068-2-20:2021 scope<\/a> separates solderability and resistance to soldering heat for devices with leads. It includes solder bath and soldering iron methods. Its public summary also directs surface-mount device soldering tests to another standard. A report should therefore identify the relevant device construction and method, rather than attaching any solder-related standard number to every terminal type.<\/p>\n<p>For procurement review, keep the two conclusions on separate lines. A terminal that wets satisfactorily under one set of conditions does not automatically establish that the surrounding assembly survives a different heat exposure. Conversely, an undamaged housing after heating does not establish the quality of the solder-wetted surface. Ask the laboratory or supplier to identify the evidence supporting each statement.<\/p>\n<h2 id=\"section-2\">Start with the exact terminal configuration<\/h2>\n<p>Record the full order code, drawing revision, terminal option and manufacturing lot before comparing results. Include terminal photographs and any supplied finish or plating identification. A product-family name can cover several connection styles, and a test on one style may not address the version being purchased.<\/p>\n<p>The <a href=\"https:\/\/onpowbutton.com\/las1-agq16h-11es-product\/\">LAS1-AGQ16H-11E\/S product page<\/a> provides a concrete ONPOW product identity to use in a technical enquiry. The photographs here identify real catalogue products. They do not establish that these particular samples underwent a soldering test or possess a specified plating composition. Request the current drawing and instructions for the actual order code.<\/p>\n<p>If the connection process is still undecided, first compare <a href=\"https:\/\/onpowbutton.com\/news\/screw-vs-solder-push-button-terminals\/\">screw and solder push button terminals<\/a>. The present review begins after a solder termination has been selected; its purpose is evidence acceptance rather than connection-style selection.<\/p>\n<figure><img decoding=\"async\" alt=\"ONPOW LAS1-AGQ16H-11\/S \u2014 original manufacturer product photograph\" loading=\"lazy\" src=\"https:\/\/onpowbutton.com\/wp-content\/uploads\/2026\/11\/push-button-solderability-heat-report-body1-daily20261108.jpg\"\/><figcaption>ONPOW LAS1-AGQ16H-11\/S.

It is an enquiry framework, not an additional set of IEC pass criteria. The method and numerical acceptance limits must come from the applicable specification and approved process.<\/p>\n<div class=\"onpow-table-scroll\">\n<table>\n<thead>\n<tr>\n<th>Review field<\/th>\n<th>What to request<\/th>\n<th>Reason to hold approval<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Sample identity<\/td>\n<td>Full switch code, terminal option, drawing and lot<\/td>\n<td>Only a family photograph is supplied<\/td>\n<\/tr>\n<tr>\n<td>Test purpose<\/td>\n<td>Separate solderability and heat-resistance conclusions<\/td>\n<td>One conclusion is used to imply the other<\/td>\n<\/tr>\n<tr>\n<td>Method<\/td>\n<td>Standard edition and selected bath or iron procedure<\/td>\n<td>Test fixture or procedure is unspecified<\/td>\n<\/tr>\n<tr>\n<td>Solder system<\/td>\n<td>Alloy, flux and relevant preparation<\/td>\n<td>Evidence uses an unidentified assembly chemistry<\/td>\n<\/tr>\n<tr>\n<td>Thermal exposure<\/td>\n<td>Controlled temperature, duration and contact arrangement<\/td>\n<td>Only the soldering station display setting is recorded<\/td>\n<\/tr>\n<tr>\n<td>Preconditioning<\/td>\n<td>Storage history and any specified conditioning<\/td>\n<td>Fresh samples are used to justify unknown stored stock<\/td>\n<\/tr>\n<tr>\n<td>Examination<\/td>\n<td>Required surface, mechanical and electrical observations<\/td>\n<td>Photographs replace the required measurements<\/td>\n<\/tr>\n<tr>\n<td>Disposition<\/td>\n<td>Results against agreed criteria, deviations and sign-off<\/td>\n<td>A \u201cpass\u201d appears without the criteria<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p><a href=\"https:\/\/knowledge.bsigroup.com\/products\/environmental-testing-tests-test-ta-and-tb-test-methods-for-solderability-and-resistance-to-soldering-heat-of-devices-with-leads\" rel=\"noopener\" target=\"_blank\">BSI&#8217;s publication overview<\/a> independently identifies the same two test purposes. Consult the complete applicable document for the test itself; this worksheet does not reproduce its procedure.<\/p>\n<h2 id=\"section-4\">Read process conditions as a complete set<\/h2>\n<p>A temperature value without exposure time and contact arrangement is difficult to interpret. Ask what was heated, where contact occurred, how the specimen was supported and whether the setup used a specified heat sink. These questions help determine whether the report represents the proposed assembly operation. They do not authorize substituting an untested arrangement.<\/p>\n<p>Keep alloy and flux records with the thermal conditions. A production change in materials or equipment should trigger a documented comparison with the qualified process. The supplier may be able to justify continued applicability, or may recommend additional validation. Avoid treating an old report as a permanent approval for every future assembly change.<\/p>\n<h2 id=\"section-5\">Distinguish wetting evidence from an attractive photograph<\/h2>\n<p>Request the stated examination method and the actual reported result. A photograph can help show the inspected area and obvious surface features, but it cannot supply an omitted test condition. If the acceptance criterion concerns a defined area, ask how that area was identified and evaluated. If the report gives only \u201cgood soldering,\u201d request the criterion that made it good.<\/p>\n<p>Do not infer terminal metallurgy from surface colour. Record the manufacturer&#8217;s declared finish and confirm that the tested terminals use that finish. Where the supplier regards a material detail as confidential, request an adequate controlled identification or written applicability statement instead of inventing the missing composition from appearance.<\/p>\n<figure><img decoding=\"async\" alt=\"ONPOW LAS1-AGQ16-11ET\/S \u2014 original manufacturer product photograph\" loading=\"lazy\" src=\"https:\/\/onpowbutton.com\/wp-content\/uploads\/2026\/11\/push-button-solderability-heat-report-body2-daily20261108.jpg\"\/><figcaption>ONPOW LAS1-AGQ16-11ET\/S. Product identification example only; this photograph does not establish soldering, biological, chemical, dielectric, thermal or moisture performance or certification. Confirm the exact ordered configuration and tested equipment scope separately.<\/figcaption><\/figure>\n<h2 id=\"section-6\">Inspect the whole switch after the heat exposure<\/h2>\n<p>A useful heat-resistance review asks which component properties were checked before and after conditioning. Depending on the applicable specification, the relevant evidence may include actuator movement, terminal retention, contact function or other required electrical examinations. The report should identify the checks actually performed; the buyer should not add unperformed checks to its conclusion.<\/p>\n<p>Compare this evidence with the separate <a href=\"https:\/\/onpowbutton.com\/news\/push-button-terminal-robustness-report\/\">terminal robustness report review<\/a>. Mechanical terminal loading and soldering heat investigate different stresses. A robust terminal can still require assembly heat limits, and heat tolerance alone does not authorize pulling or bending a termination during harness installation.<\/p>\n<h2 id=\"section-7\">Account for storage and component handling<\/h2>\n<p>Clarify whether the tested samples represent newly manufactured terminals or the storage condition expected at assembly. Keep packaging date, storage instructions and traceability with incoming inspection records. If stored stock behaves differently during assembly, investigate that difference rather than automatically increasing temperature or extending contact time.<\/p>\n<p>A practical investigation compares affected and unaffected lots, checks process records, preserves representative unused samples and asks the supplier for guidance. It should also examine whether the observed issue concerns wetting, contamination, handling damage or a different terminal option. This avoids changing several variables at once and losing the ability to identify the cause.<\/p>\n<h2 id=\"section-8\">Treat rework as a separate approval question<\/h2>\n<p>An initial assembly exposure does not establish unlimited rework capability. Ask whether the manufacturer&#8217;s instructions address reheating, repeated soldering or replacement, and whether the qualification included those conditions. Where no allowance is documented, obtain guidance before adding rework cycles to the production instruction.<\/p>\n<p>Record rework operations by lot and station when investigating damage. A component can look acceptable after assembly while an omitted functional check leaves uncertainty about its condition. The appropriate response is to complete the specified inspection and resolve the process deviation, rather than relying on visual appearance alone.<\/p>\n<h2 id=\"section-9\">Example of a purchasing decision<\/h2>\n<p>Consider a hypothetical panel builder receiving two documents. The first lists a product family, an iron temperature and \u201cpass.\u201d The second names the exact terminal drawing, separates the two test purposes, records the exposure conditions and includes the required examination results. Neither document should be accepted solely because it is longer. The second offers the information needed for an engineering comparison; the first requires clarification.<\/p>\n<p>Suppose the second report covers a different terminal finish from the quoted switch. Mark that difference as unresolved. Request a written explanation linking the result to the ordered version, or request the correct evidence. Do not silently copy the tested finish into the purchase order if it was never offered. This protects both the buyer&#8217;s specification and the supplier&#8217;s declared scope.<\/p>\n<p>A useful disposition states \u201caccepted for the identified assembly process,\u201d \u201cadditional evidence required,\u201d or \u201cconfiguration mismatch.\u201d Give the reason and responsible reviewer. This is more actionable than an unqualified compliance label because the production team can see exactly which process and component were assessed.<\/p>\n<h2 id=\"section-10\">Prepare an enquiry that can be answered<\/h2>\n<p>Send ONPOW the full switch code, quantity, intended connection method, solder alloy and flux information, expected storage period, proposed assembly exposure and required inspection criteria. Include any customer standard and its edition. Ask for current handling instructions, applicable reports and confirmation of the supplied termination.<\/p>\n<p>Keep the approved evidence with the drawing and assembly instruction. When a terminal option or production process changes, reopen the applicability review. For the laboratory side, the <a href=\"https:\/\/onpowbutton.com\/news\/push-button-laboratory-accreditation-scope\/\">accreditation scope checklist<\/a> explains why a laboratory name alone does not establish that the particular method falls within its scope.<\/p>\n<h2 id=\"section-11\">Frequently asked questions<\/h2>\n<h3>Does a solderability pass establish resistance to soldering heat?<\/h3>\n<p>No. The two purposes require their own applicable evidence. Review the stated method, conditions and result for each instead of extending one pass statement to both properties.<\/p>\n<h3>Can a temperature from another switch be used for this model?<\/h3>\n<p>Use the exact manufacturer&#8217;s instructions and an approved assembly process. A different terminal, housing or arrangement may fall outside the evidence, even when the switches look similar.<\/p>\n<h3>Is a soldered sample photograph enough for purchasing approval?<\/h3>\n<p>It is supporting identification evidence. The report still needs sample traceability, test conditions, acceptance criteria and the required examination results before an engineering reviewer can assess applicability.<\/p>\n<h3>What should be requested if the supplied report covers another terminal finish?<\/h3>\n<p>Request the correct report or a controlled applicability explanation from the supplier. Keep the difference open until the responsible reviewer accepts the evidence for the ordered configuration.<\/p>\n<h2 id=\"learning-video\">Further learning<\/h2>\n<p>Heat transfer explains why assembly exposure involves time and the component heat path.
